Trigs
What is trigs about? Why is trigs important to life? Give examples of trigs used in life? What is the difference between 3D trigs and 2D trigs? Which trigs do you enjoy or used more 2D or 3D? Give examples of how you use 3D trigs?
trigs are used in everyday life for instance when you cross a field you do not go around the sides you go straight across since it is faster, also use when you angle light at an object the further away you go the more area that light covers, used in building buildings, bridges, and things used in everyday life like cars, phones and throwing things in the bins.
2D trig have (x,y coordinates) to show height and width while 3D trigs have (x,y,z coordinates) for the purpose of creating the illusion of height, width and depth.
Trigonometry is the mathematics of triangles and trigonometric functions, such as SINE, COSINE and TANGENT. A trigonometric function is defined as the function of an angle expressed as the ratio of the lengths of the sides of a right-angle triangle...namely: OPPOSITE, ADJACENT and HYPOTENUSE
trigs are important to life as they allow for calculation of angles and distances by triangulating the location of certain points. It also allows for design and testing of structures still to be built, as trigonometry is vital in construction and architecture
Examples of trigs in life: 1) In designing buildings and houses 2) Calculations for theoretical load-shedding across a bridge 3) In the lifting and placing of loads by a crane
2D or 2 Dimensional trigs deals with trigonometry in one plane, such as a sheet of paper, where as 3D or 3 Dimensional trigs deals with trigonometry in all planes, being a real structure
I enjoy using 3D trigs more than 2D trigs, mainly because it is more practical, as in the case of forces, they don't act in one direction, but in all directions, and 3D allows one to understand how the forces are acting about a single point. P.S. ( If you are asking this because you are thinking what to bring for exams, i prefer 2-D trigs because they easier to do...LOL)
3D trigs would be used to fully understand how forces are distributed throughout a body, such as, again, on a bridge, and also, as in the example miss gave i think today or yesterday, with the 2 guys looking up at the lighthouse on the cliff, it allows to see how the men were located at the bottom of the cliff easier, when calculating the distance between the men
Trigonometry is based upon the shape called the triangle. In trigs, calculations are made using the fact that triangles all possess three sides and three angles and also shows the relationships between these components.
Life is filled with angles.Everywhere you turn, you can be sure to see them in some way or another. Trigs can be used to determine distances, heights of objects, angles between contact surfaces. Engineers can use trigonometry to formulate and test the design of buildings, bridges and other architectual structures 'on paper', as it were, before the actual implementation of the project.
examples of trigs used in life can be: surveyers...um, surveying land; acts performed automatically by the brain such as looking at two faraway objects and deciding which is taller, averaging the distance between two objects and figuring out whether can throw an object through them from our present position, for eg,as Green Lantern mentioned - throwing garbage into the bins...there may be countless other examples
two dimensional trigonometry is shown on two planes and basically consists of height and width, while three dimensional trigonometry has three planes and gives us height, width and also depth, creating a real life structure to which we can probably relate.
while two dimensional problems are easier to do, three dimensional ones are more fun to do and give us the opportunity to see things from different perspectives and also to think more deeply and so i enjoy doing these more.
trig is important in life because it deals mostly with angles and well angles are essential in life thus trigs is important....if not everything in life would be straight and boring...so thank god for angles...
the difference between 2d and 3d is that 2d is flat on one plane while 3d and on a 3 bases axis where u can see height length and even volume.2d objects are just based on what you could see and just the sides and area. but when you take the 2d object and rotate it about the x or y axis and you get a 3d object you can use that to find volume are surface area the base and height.
you can create a 3d shape.for example,if one end of the line is fixed and the rotation is circular and at an angle,i.e.not along the x-axis or y-axis but rather on the z-axis, if you can trace the path created by the line, you will find that you have a cone shape being formed: a three dimensional object
the same thing applies there too i think...if the line is vertical, and one end is fixed, then you will still get a cone being formed, just in another direction...
trigs...what is trigs really? trigs is about triangles, triangles in-turn are about angles, whether is it angles of elevation, angles of depression or the angle between two objects or bodies. Without trigs, we would not have any high rise buildings what so ever and is therefore important to life. i think that's the jist of it, not very detailed but i tried
trigs is about triangles. in trigs we use the three ratios sin, cos and tan.
trigs are used in: -designs -people looking at objects at differnt angles
2d trigs are less used than 3 d trigs. the differnece is 2d trigs is dealing with 2 dimensional figures and 3d trigs is dealing with three dimensional figures.
trigs is important in life to give angles and also to show how you formulate things.
3d trigs is used by sea men, looking at things at different angles. they are at one point but they are looking at a tower on the top of a cliff located 110km away from them.
i used trigs when i was working on a roof to calculate the different angles most of these builders construct thing without knowing the maths behind it they just use rough calculations and get the job done another (eg) would be putting down tiles on your floor.
WHAT IS TRIGS/TRIGONOMETRY trigonometry which literally means triangle measure is the study of the elements of triangles relate to each other e.g. pythagorous theorum is a relationship between the line segments of a right angled triangle ,while e.g. is derived from understanding the relationship between the line segments and the angles of a right angled triangle. one can think of the right angled triangle as a basic triangle ,which is used to study and develope formulas for more irregular triangles
i enjoy 2D trigs. 3D trigs are simple though. i have never did this before. but am willing and i have to do it. am guessing its simple. just like 2D trisgs but more triangles?
sometimes the real world gives us a river that is too difficult to cross or a cliff too dangerous to climb. In these cases the physical approach isn’t possible. We need trigonometry--a mathematical technique we can trust for the answers we need.
A common real life problem that may be solved using the rules of trigonometry is to work out the measurements of things that would be difficult to measure directly.
what is trigs?Trigonometry is a branch of mathematics that deals with triangles, particularly those plane triangles in which one angle has 90 degrees (right triangles). Trigonometry deals with relationships between the sides and the angles of triangles and with the trigonometric functions, which describe those relationships.do u agree????
why is trigs important?well Trigonometry is necessary any time there is an angle involved (the angle of the sun, the angle of the cue ball in a game of pool...) or any time you have to compare two non-parallel lines (the height of a building and the height of its shadow, the distance a train is from the crossing and the distance a car is from the crossing). These kinds of problems cannot easily be solved without trig.
Why is trigs important to life? The reason why trigs is so important to life lies all around us everyday. To illustrate this i'll answer this question with a question.... Do you think blue prints to construct buildings can be made without using trigs...?
Give examples of how you use 3D trigs? i use 3D trigs for home projects. like my dog kennel. i didn want to make mistakes so i used trigs to calculate things like the length of the roof support and so on............
Trigs delas with the relationship between angles and sides of a triangle. There are 6 major trigonometrical functions used in modern mathematics, they are cosine,sine,tangent,secant,cotangent and cosecant. However, at our present level we mainly use the cosine,sine and tangent rules. The study of trigs are not limited to these three rules,such theories as Pythagorsus' theorem exsists and are used to find solutions to right angled triangles. In a nutshell, i would say trigs is the study of Triangles...
Trigs is very important in life...where would we be without these formulas and functions...application of this topic in mathematics vary widely.Engineers,scientists,surveyors, astronomers, architects,pilots ect. the lists goes on and on.
People use trigs to work out real life problems theoretically, when the traditional way is difficult or cannot be done. Such as the heights of mountains, the quantity of water in a lake, or the square footage of a piece of land that is an unusual shape.
Trigonometry can even be used to help astronomers measure time accurately.
trigs deals with triangles and the importance in everyday life are the lengths and the angles. eg: we try as much as possible to walk on a hypotenuse as it is shorter than walking two lengths. without triangles walking and returning to our starting position would be take much longer........
trigs is important in life. it is used to calculate the height of mountains and tall structures. we use trigs everyday when we go up and down the stairs.
trigs........triangles trigonometry is used to work out angles and lenght of siges in a triangle. A triangle could be any three points that have a connection and you can get a triangle from many other shapes squares a slice of pizza example you going to canada from trinidad and have to stop at miami before.
in 2D trigs you think if one flat triangle.
3D trigs,that makes I think of real life situations more than one triangles or shapes are involved because there are so many other elements out of our control that affect our end point like there's an emergency and the plane has to stop somewhere else before it reaches canada
that's where blue prints come in able to observe each situation carefully without being confued by other point and dimensions we use blue prints a blue print shows an object from one view point when we are told to draw the separate triangles in class, we are making blue prints but of a simple situation
Trigonometry finds a perfect partner in modern architecture. The beautifully curved surfaces in steel, stone and glass would be impossible if not for this science. So how does this work actually. In fact the flat panels and straight planes in the building are but at an angle to one another and the illusion is that of a curved surface.BASIC!
THE DIFFERENCE BETWEEN 2D AND 3D 2D refers to ‘flat’, using the X & Y (horizontal and vertical) axis’, the image has only two dimensions and if turned to the side becomes a line. 3D adds the ‘Z’ dimension. This third dimension allows for rotation and depth. It’s essentially the difference between a painting and a sculpture.
I hav'nt used alot of 3d trigs but i naturally like it more because it fells more relavant to the real world and not like just playing around with the properties of a triangle
the difference between 2D and 3D trigs is that if u hav a 2D square figure u can find the area and perimeter but a 3D square which is called a cuboid u can find the area,perimeter and the volume
Some example for which we use trigs in our everyday life are music .music is a sound and sound is said to travel in waves and nearly everyday humans upload and download music onto there computers.But the computer can not listen an understand the music like we do.In fact it use trigs in order to calculate the wave lenght to make up or reproduce the sound .and as such it uses the sine or cosine function
Another example of trigs used in real life are when someone is standing on the ground or roof of a building and is looking down or up .We tend to average how tall the building is or how far down are is the drop off the build .All of the entails trigs because angles of elevation and depression is a part of trigs .
2. Trigs are all around us in our every day life therefor they are very imporant since life does not exsist without angles.For example the gift of sight.Imagein not being able to roll your eyes around in different directions hence forming angles. TRY IT, SEE HOW IMPORTANT IT IS.
3. Some examples of trigs in everyday life are-: a)Sitting upright on a chair,if observed the knees bend the legs approximately at an angle of 90^C to the ground. b)When typing the arms are also bent at different angles depending on the hight of the table. c)Angles are also formed when walking or looking at objects in different directions.
4. 3D trigs are different from 2D trigs i believe because 3Ds are viewed in three dimensions which brings it to life while 2D trigs are two dimensional i.e viewed on a flat plane.
5. I like both 2D and 3D. I like 2D because its more easier and strightforward and i like 3D because its more challenging and puts me out of my comfort zone so it feels good when i can figer it out, that is when i figer it out....lol.
Yes i agree with snowwhite...3D deals with three dimentional shapes,while 2D deals with two dimentional...a diagram of a 3D object can be represented on a graph by the x axis,y axis and z axis showing height, width and depth. However 2D objects are flat,you cannot see all the dimentions of the object,and diagram of a 2D object can be represented on a graph by the x and y axis only,showing height and width.
I enjoy solving 2D trigs because it is easier and simple. Although on the other hand 3D trigs can be interesting. It tickles the mind and make you think unconventionally. When you are given a 3D trigs question to solve,you actually have to use your imagination.I think it is more realistic to solve 3D trigs though.
At my present level of study,i think i use 2D trigs more than i use 3D trigs...like solving for lengths and sides of a triangle given 2 sides and an angle etc.
Trigs are imporant in life because they are used to determine the best possible designs of things yet to be constructed. they are used to get jobs done faster because of the use of angles. They can be used to determine distance. trigs is maths and maths is life so trigs is life
An example of when trigs is used in life is in the arcitectural designs of buildings. Trigs is used to determine the angle needed between the beams of the building, the height of the walls, the distance between the beams for the strongest support of the force acting upon it.
I use 3D trigs for the construction of a kite's compass. The compass needs to be constructed so that the angle used can hold the kite upright to capture the air waves.
trigs are used everyday in life. an example of this is our sight trigs is about angles and we look at things at angles otherwise we will see at one level we can't see things behind us or to the side or on top or bottom and who knows we can loss our life like that.
Trigs is the study of how the sides and angles of a triangle are related to each other. triangles have three sides and three angles.from these sides and angles we get trig functions. these functions deals with the ratios of sides and angles
Trigonometry is a branch of mathematics that studies triangles, particularly right triangles. Trigonometry deals with relationships between the sides and the angles of triangles and with the trigonometric functions, which describe those relationships, as well as describing angles in general and the motion of waves such as sound and light waves.
Trigs are important to our lives in many ways.The primary application of trigonometry is found in scientific studies where precise distances need to be measured. The techniques in trigonometry are used for finding relevance in navigation particularly satellite systems and astronomy, naval and aviation industries, oceanography, land surveying, and in cartography (creation of maps). Now those are the scientific applications of the concepts in trigonometry, but most of the math we study would seem (on the surface) to have little real-life application. So is trigonometry really relevant in your day to day activities?
yup trigs acutually is relevent to our day to day activity!!!!lol......it was suprising to me to....lol Trigonometry finds a perfect partner in modern architecture. The beautifully curved surfaces in steel, stone and glass would be impossible if not for the immense potential of this science, the flat panels and straight planes in the building are at an angle to one another and the illusion is that of a curved surface. Neat huh!
Did you know that trigonometry is an arty science that can be used to measure the heights of mountains? So why would we want to measure the heights of mountains? Because this information is of great value for aircraft designing and navigation. And if this sounds overly technical think about the last time you went up to maracus waterfalls. You might be surprised to know how much this information comes in handy to tourists, for example those with medical conditions that prevent them from traveling to very high altitudes.So suprisingly trigs is very important to life. so the next time you're sitting in maths class and ask yourself OMG why do i have to be here think about this.LOL
2D and 3D refer to the actual dimensions of a trig. 2D is 'flat', using the X & Y (horizontal and vertical) axis', the image has only two dimensions and if turned to the side becomes a line. 3D adds the 'Z' dimension. This third dimension allows for rotation and depth. It's essentially the difference between a painting and a sculpture.
trigs are all about angles and lines which create them. trigs are to do with angles which are made by two straight lines which intersect at a point to make an angle. also by using the length of the lines u could find the angle which have been created by the 2 lines.
trigs. mean triangle measurement.ratios in the form of the trigs functions.the ratios are sine,cosine and tan. these ratios are used to solve right angle triangles. to slove non right angle trianges the sine and cosine rule are used.
trigs are used everyday for example when you walk up the stairs, you walk in a angle of elevation, when you walk down the stairs you walk in a angle of depression. when u walk up the road u walk in a straight line.when you look up you elevate your eyes.when you bend you turn in an angle.
2D and 3D trigs are different. 2D are easier to solve but the 3D are beter to look at when understanding trigonometry becuse it gives a clearer picture about triangles and help in understand trigs.it gives a better visual image and is nice to understand. dats what i think!!!
trigs are used in building houses,malls,in any construction of shelters, building and designing equipments and machinery. since trigs are measurements it can be used in mostly everything in everyday life.
Trigonometry is about angles and triangles, there are relationships between the angles and the ratios of the lengths of side of the triangles. These ratios are represented by functions such as sine and cosine, which occur widely in mathematics
all types of trigs be it 2d o 3d are important to life as they allow for calculation of angles and distances is useful in everyday life.wid out trigs life wud b very complicated
trigonometry is important any time there is an angle involved for example the angle of the sun, the angle of the cue ball in a game of pool or any time you have to compare two non-parallel lines for example the height of a building and the height of its shadow.
2D (2dimension) trig have height and width and has coordinates (x,y) while 3D (3dimension) trigs have height, width and depth and has coordinates (x,y,z)
1. the pilot of an aircraft flying due South, at an altitude of 750m, sees an airfield directly ahead, angle of depression 17°. at the same time the pilot notices a town due east, angle of depression 10°. how far is town from airfield?
2.from the top of a cliff 120m above sea level a boat is observed due North, angle of depression 20°. the boat travels due east and, 10min later, its angle of depression from the top of the cliff is 10°. how fast is the boat moving?
example of trigs in life: a man chooses to build a bow(the foremost point of the hull of a ship) of his ship in the shape of an issoceles triangle for better balance on the water
trigs is based on triangles which are shapes formed by connecting three straight lines. tri angles, from the word it self it can be seen that it consist of three angles which could form either right angled triangles or non-right angled triangles.
trigs are very important in life. trigs are used to work out real problems in every day life. some examples of trigs in everyday life are:when driving a car when building houses constructing bridges and other constructions which requires accuracy.

I have been exploring information about the swimming pool filtration plant for a long time now due to the project I am currently working on and so far perhaps this is the best website I have came across.
Why not allow our creator, Jesus, to show His love? Make Him your best friend by telling him the things you tell your best friend. When Jesus is part of your everyday life, well you are on top of the world. The best things will happen and the trials will be testing but the best for you will prevail.
trigs are used in everyday life for instance when you cross a field you do not go around the sides you go straight across since it is faster, also use when you angle light at an object the further away you go the more area that light covers, used in building buildings, bridges, and things used in everyday life like cars, phones and throwing things in the bins.
ReplyDeletetrigs is about triangles 3 dimensional objects
ReplyDelete2d trigs are two dimensions and 3d is 3 dimension
ReplyDeleteMy answer would be the relationships between the sides and angles of triangles.
ReplyDeleteWaves in the sea are an example of a sine wave, trigs are also important for architects
2D trig have (x,y coordinates) to show height and width while 3D trigs have (x,y,z coordinates) for the purpose of creating the illusion of height, width and depth.

sorry miss i'm tired you kno what i'm saying right
ReplyDeletei ment more irregular shapes
ReplyDeleteto get help with the 3D trigs, simply use your surroundings. take pieces of paper and build and shape. using this you can observe different triangles
ReplyDeletei enjoy 2D trigs. 3D trigs are simple though. i have never did this before. but am willing and i have to do it. am guessing its simple. just like 2D trisgs but more triangles?

However, at our present level we mainly use the cosine,sine and tangent rules. The study of trigs are not limited to these three rules,such theories as Pythagorsus' theorem exsists and are used to find solutions to right angled triangles. In a nutshell, i would say trigs is the study of Triangles...
ReplyDeleteTrigs is very important in life...where would we be without these formulas and functions...application of this topic in mathematics vary widely.Engineers,scientists,surveyors, astronomers, architects,pilots ect. the lists goes on and on.
ReplyDeletePeople use trigs to work out real life problems theoretically, when the traditional way is difficult or cannot be done.
Such as the heights of mountains, the quantity of water in a lake, or the square footage of a piece of land that is an unusual shape.
Trigonometry can even be used to help astronomers measure time accurately.
Trigs is very important in everyday life.

ReplyDeletetrigs is a branch of mathematics that deals with triangles. mainly right triangles, i.e plane triangles
ReplyDeletetrigs dealts with the relationship between the sides and the angles of a trianle
ReplyDeletetrigs deals with triangles and the importance in everyday life are the lengths and the angles.
ReplyDeleteeg: we try as much as possible to walk on a hypotenuse as it is shorter than walking two lengths. without triangles walking and returning to our starting position would be take much longer........
trigs is important in life. it is used to calculate the height of mountains and tall structures. we use trigs everyday when we go up and down the stairs.
ReplyDeletetrigs........triangles
ReplyDeletetrigonometry is used to work out angles and lenght of siges in a triangle.
A triangle could be any three points that have a connection and you can get a triangle from many other shapes squares a slice of pizza
example
you going to canada from trinidad and have to stop at miami before.
in 2D trigs you think if one flat triangle.
3D trigs,that makes I think of real life situations more than one triangles or shapes are involved because there are so many other elements out of our control that affect our end point
like there's an emergency and the plane has to stop somewhere else before it reaches canada
that's where blue prints come in able to observe each situation carefully without being confued by other point and dimensions we use blue prints
a blue print shows an object from one view point
when we are told to draw the separate triangles in class, we are making blue prints but of a simple situation
Trigonometry finds a perfect partner in modern architecture. The beautifully curved surfaces in steel, stone and glass would be impossible if not for this science. So how does this work actually. In fact the flat panels and straight planes in the building are but at an angle to one another and the illusion is that of a curved surface.BASIC!
ReplyDeleteTHE DIFFERENCE BETWEEN 2D AND 3D
ReplyDelete2D refers to ‘flat’, using the X & Y (horizontal and vertical) axis’, the image has only two dimensions and if turned to the side becomes a line. 3D adds the ‘Z’ dimension. This third dimension allows for rotation and depth. It’s essentially the difference between a painting and a sculpture.
I hav'nt used alot of 3d trigs but i naturally like it more because it fells more relavant to the real world and not like just playing around with the properties of a triangle
ReplyDeleteFEELS, BASIC!
ReplyDeletetrigs are about 2D and 3D triangles.You use formula's like sine rule,cosine rule,tan,sine and cos to obtain values(angles and lengths)on the triangle.
ReplyDeletethe difference between 2D and 3D trigs is that if u hav a 2D square figure u can find the area and perimeter but a 3D square which is called a cuboid u can find the area,perimeter and the volume
ReplyDeletetrigs is a part of geometry which deals with the study of triangles.It is the study of right angle triangles.
ReplyDeleteSome example for which we use trigs in our everyday life are music .music is a sound and sound is said to travel in waves and nearly everyday humans upload and download music onto there computers.But the computer can not listen an understand the music like we do.In fact it use trigs in order to calculate the wave lenght to make up or reproduce the sound .and as such it uses the sine or cosine function
ReplyDeleteI forget to say that trigs uses the Pythagorean Theorem ,sine ,cosine rule in order to solve for the triangles .
ReplyDeleteAnother example of trigs used in real life are when someone is standing on the ground or roof of a building and is looking down or up .We tend to average how tall the building is or how far down are is the drop off the build .All of the entails trigs because angles of elevation and depression is a part of trigs .
ReplyDelete1. Trigs i believe discribe triangles which consist of angles which shows a comparision between two stright lenghts.
ReplyDelete2. Trigs are all around us in our every day life therefor they are very imporant since life does not exsist without angles.For example the gift of sight.Imagein not being able to roll your eyes around in different directions hence forming angles. TRY IT, SEE HOW IMPORTANT IT IS.
ReplyDelete3. Some examples of trigs in everyday life are-: a)Sitting upright on a chair,if observed the knees bend the legs approximately at an angle of 90^C to the ground.
ReplyDeleteb)When typing the arms are also bent at different angles depending on the hight of the table.
c)Angles are also formed when walking or looking at objects in different directions.
4. 3D trigs are different from 2D trigs i believe because 3Ds are viewed in three dimensions which brings it to life while 2D trigs are two dimensional i.e viewed on a flat plane.
ReplyDelete5. I like both 2D and 3D. I like 2D because its more easier and strightforward and i like 3D because its more challenging and puts me out of my comfort zone so it feels good when i can figer it out, that is when i figer it out....lol.
ReplyDeleteSo i ges i could say i use 2D more but i enjoy 3D more.
ReplyDeletetrigs are abot triangles and from the word triangle we get three angles.
ReplyDeleteYes i agree with snowwhite...3D deals with three dimentional shapes,while 2D deals with two dimentional...a diagram of a 3D object can be represented on a graph by the x axis,y axis and z axis showing height, width and depth. However 2D objects are flat,you cannot see all the dimentions of the object,and diagram of a 2D object can be represented on a graph by the x and y axis only,showing height and width.
ReplyDeleteI enjoy solving 2D trigs because it is easier and simple. Although on the other hand 3D trigs can be interesting.
ReplyDeleteIt tickles the mind and make you think unconventionally. When you are given a 3D trigs question to solve,you actually have to use your imagination.I think it is more realistic to solve 3D trigs though.
At my present level of study,i think i use 2D trigs more than i use 3D trigs...like solving for lengths and sides of a triangle given 2 sides and an angle etc.
ReplyDeleteTrigs as the name implies, deals with triangles. three lines connected together by three angles.
ReplyDeleteTrigs are imporant in life because they are used to determine the best possible designs of things yet to be constructed. they are used to get jobs done faster because of the use of angles. They can be used to determine distance. trigs is maths and maths is life so trigs is life
ReplyDeleteAn example of when trigs is used in life is in the arcitectural designs of buildings. Trigs is used to determine the angle needed between the beams of the building, the height of the walls, the distance between the beams for the strongest support of the force acting upon it.
ReplyDelete2D trigs uses height and width. while 3D trigs has height, width and depth. 2D are only flat while 3D trigs is three dimensional solid objects
ReplyDelete2D trigs is the one used the most and i do enjoy it the most.
ReplyDeleteI use 3D trigs for the construction of a kite's compass. The compass needs to be constructed so that the angle used can hold the kite upright to capture the air waves.

ReplyDeletetrigs are used everyday in life. an example of this is our sight trigs is about angles and we look at things at angles otherwise we will see at one level we can't see things behind us or to the side or on top or bottom and who knows we can loss our life like that.
ReplyDeletei enjoy 3D triangles because within a 3D shape you can actually see the shape of something but by using a 2D shape you can't see the shape in anything
ReplyDeleteTrigs is the study of how the sides and angles of a triangle are related to each other. triangles have three sides and three angles.from these sides and angles we get trig functions. these functions deals with the ratios of sides and angles
ReplyDeletetrigs are basically about triangles and the angles contained within them
ReplyDeletetrig are used when constructing a simple gable roof in order to determine the lengths of galvanize to be used
ReplyDeleteTrigonometry is a branch of mathematics that studies triangles, particularly right triangles. Trigonometry deals with relationships between the sides and the angles of triangles and with the trigonometric functions, which describe those relationships, as well as describing angles in general and the motion of waves such as sound and light waves.
ReplyDeleteTrigs are important to our lives in many ways.The primary application of trigonometry is found in scientific studies where precise distances need to be measured. The techniques in trigonometry are used for finding relevance in navigation particularly satellite systems and astronomy, naval and aviation industries, oceanography, land surveying, and in cartography (creation of maps). Now those are the scientific applications of the concepts in trigonometry, but most of the math we study would seem (on the surface) to have little real-life application. So is trigonometry really relevant in your day to day activities?
ReplyDeleteyup trigs acutually is relevent to our day to day activity!!!!lol......it was suprising to me to....lol Trigonometry finds a perfect partner in modern architecture. The beautifully curved surfaces in steel, stone and glass would be impossible if not for the immense potential of this science, the flat panels and straight planes in the building are at an angle to one another and the illusion is that of a curved surface. Neat huh!
ReplyDeleteDid you know that trigonometry is an arty science that can be used to measure the heights of mountains? So why would we want to measure the heights of mountains? Because this information is of great value for aircraft designing and navigation. And if this sounds overly technical think about the last time you went up to maracus waterfalls. You might be surprised to know how much this information comes in handy to tourists, for example those with medical conditions that prevent them from traveling to very high altitudes.So suprisingly trigs is very important to life. so the next time you're sitting in maths class and ask yourself OMG why do i have to be here think about this.LOL
ReplyDelete2D and 3D refer to the actual dimensions of a trig. 2D is 'flat', using the X & Y (horizontal and vertical) axis', the image has only two dimensions and if turned to the side becomes a line. 3D adds the 'Z' dimension. This third dimension allows for rotation and depth. It's essentially the difference between a painting and a sculpture.
ReplyDeletei prefer to use 3D trigs because it makes the question trying to be answered more real and makes maths/trigs so much more interesting.
ReplyDeletetrigs are all about angles and lines which create them. trigs are to do with angles which are made by two straight lines which intersect at a point to make an angle. also by using the length of the lines u could find the angle which have been created by the 2 lines.
ReplyDeletetrigs are important to life as they allow for calculation of angles and distances is useful in everyday life
ReplyDeletetrigs are about angles and distances, calculating these are useful in life taking into consideration what it may be used for
ReplyDeletetrigs. mean triangle measurement.ratios in the form of the trigs functions.the ratios are sine,cosine and tan. these ratios are used to solve right angle triangles. to slove non right angle trianges the sine and cosine rule are used.
ReplyDeletetrigs are used everyday for example when you walk up the stairs, you walk in a angle of elevation, when you walk down the stairs you walk in a angle of depression. when u walk up the road u walk in a straight line.when you look up you elevate your eyes.when you bend you turn in an angle.
ReplyDelete2D and 3D trigs are different. 2D are easier to solve but the 3D are beter to look at when understanding trigonometry becuse it gives a clearer picture about triangles and help in understand trigs.it gives a better visual image and is nice to understand. dats what i think!!!
ReplyDeletetrigs are used in building houses,malls,in any construction of shelters, building and designing equipments and machinery. since trigs are measurements it can be used in mostly everything in everyday life.
ReplyDeleteTrigonometry is about angles and triangles, there are relationships between the angles and the ratios of the lengths of side of the triangles. These ratios are represented by functions such as sine and cosine, which occur widely in mathematics
ReplyDelete2d trigs are easier to solve and interpret while 3d trigs are more challenging
ReplyDeletebut 3d trigs are more exciting although challenging.u get to visualize and have a better understanding of a situation and its angles and triangles.
ReplyDelete3d trigs are used in building houses,malls,aeroplanes,pratically everyting dat is 3d.
ReplyDeleteall types of trigs be it 2d o 3d are important to life as they allow for calculation of angles and distances is useful in everyday life.wid out trigs life wud b very complicated
ReplyDeletetrigs is the study of triangles and deals with relationships between sides and angles of the triangles with their functions
ReplyDeletetrigonometry is important any time there is an angle involved for example the
ReplyDeleteangle of the sun, the angle of the cue ball in a game of pool or
any time you have to compare two non-parallel lines for example the height of a
building and the height of its shadow.
2D (2dimension) trig have height and width and has coordinates (x,y) while 3D (3dimension) trigs have height, width and depth and has coordinates (x,y,z)
ReplyDelete1. the pilot of an aircraft flying due South, at an altitude of 750m, sees an airfield directly ahead, angle of depression 17°. at the same time the pilot notices a town due east, angle of depression 10°. how far is town from airfield?
ReplyDelete2.from the top of a cliff 120m above sea level a boat is observed due North, angle of depression 20°. the boat travels due east and, 10min later, its angle of depression from the top of the cliff is 10°. how fast is the boat moving?
example of trigs in life: a man chooses to build a bow(the foremost point of the hull of a ship) of his ship in the shape of an issoceles triangle for better balance on the water
ReplyDeleteA 2D shape is a plain figure and 3D is 3 dimensional example a block 2m high, 3m long and 5m breath
ReplyDeletea block is a 3d figure and is used for the building of houses
ReplyDeletetrigs is based on triangles which are shapes formed by connecting three straight lines. tri angles, from the word it self it can be seen that it consist of three angles which could form either right angled triangles or non-right angled triangles.
ReplyDeletetrigs are very important in life. trigs are used to work out real problems in every day life. some examples of trigs in everyday life are:when driving a car when building houses constructing bridges and other constructions which requires accuracy.
ReplyDeleteome examples of trigs in everyday life are:when driving a car when building houses constructing bridges, building stairs and other constructions which requires accuracy.
ReplyDeletethat suppose 2 be some eh mistype"Some"
ReplyDelete2D trigs have height and width while 3D trigs has height, width and depth.
ReplyDelete3 d trigs since it is more realistic.
ReplyDelete3d trigs are used on mostly everything being constructed in real life. it is used in building houses,cars, airplanes, bridges etc
ReplyDeletetris are basically about triangles.....which consists of 3 sides and simply made up of angles!
ReplyDeleteTri
Angle :)
Mathematics is a subject that requires precise and exact results...and trigs is a very reliable method for this.
ReplyDeleteTake a house for example...how the walls are built and especially the modern ceilings are built using angles. these are put together using trigs!
ReplyDelete2D is simply flat...or 1 sided, but 3D can be viewed from a 360 degress....meaning it can be seen from all around. This applies to triangles
ReplyDeleteHonestly....lol....i enjoy 2D cause its easier...and trigs isn't my strongest :(
ReplyDeletewhen u hear trigs, u think about triangles
ReplyDeletesince angles are everywhere,with trigs u can cal. angles and lengths in life
ReplyDeletedriving a car, building houses are real life situations
ReplyDelete3d trig are more interesting as u are allowed to use ur imagiation to picture the triangles
ReplyDelete2D trigs have height and width while 3D trigs has height, width and depth.
ReplyDeleteTrigonometry is the mathematics of triangles and trigonometric functions, such as SINE, COSINE and TANGENT.
ReplyDeleteA trigonometric function is defined as the function of an angle expressed as the ratio of the lengths of the sides of a right-angle triangle...namely: OPPOSITE, ADJACENT and HYPOTENUSE
trigs are important to life as they allow for calculation of angles and distances by triangulating the location of certain points. It also allows for design and testing of structures still to be built, as trigonometry is vital in construction and architecture
ReplyDeleteExamples of trigs in life:
ReplyDelete1) In designing buildings and houses
2) Calculations for theoretical load-shedding across a bridge
3) In the lifting and placing of loads by a crane
2D or 2 Dimensional trigs deals with trigonometry in one plane, such as a sheet of paper, where as 3D or 3 Dimensional trigs deals with trigonometry in all planes, being a real structure
ReplyDeleteI enjoy using 3D trigs more than 2D trigs, mainly because it is more practical, as in the case of forces, they don't act in one direction, but in all directions, and 3D allows one to understand how the forces are acting about a single point.
ReplyDeleteP.S. ( If you are asking this because you are thinking what to bring for exams, i prefer 2-D trigs because they easier to do...
3D trigs would be used to fully understand how forces are distributed throughout a body, such as, again, on a bridge, and also, as in the example miss gave i think today or yesterday, with the 2 guys looking up at the lighthouse on the cliff, it allows to see how the men were located at the bottom of the cliff easier, when calculating the distance between the men
ReplyDeleteAn example of when trigs is used in life is in the designs of buildings to determine the angle
ReplyDeleteTrigs are important they are part of who we are i mean without trigonometry we cant build vast structures that our country dwells on today
ReplyDelete3d trigs are much easier than 2d trigs because they give you a broader outlook on how the triangle really is
ReplyDeleteI enjoy 3D trigs but working 2D is simpler
ReplyDeletegraphics in games object in real life are all 3D, soo why not work out equation in real life to get a better understanding of how things are.
ReplyDeleteWE USE 3D TRIGS TO BUILD HOUSES AND TALL BUILDINDS BECAUSE WE NEED TO KNOW WHAT ANGLES ARE SUITABLE FOR WHAT HEIGHT
ReplyDeletewhen trying to understand a word Mom always has us break the word up, and then put it back together to c y the meaning is such.
ReplyDeletehas anyone ever tried that approach even when she asks question in class break up the word into syllabs and getting the meaning for each it helps.
ReplyDeleteTrigs are imporant in life because they are used to determine different angles
ReplyDeleteAn example of when trigs is used in life is in the designing of buildings
ReplyDelete2D trigs is the one used the most since it is less complicated
ReplyDelete3D trig is more indept since it deals with a little more detail than 2D because it has to deal with the dept of the triangle
ReplyDeleteTrigonometry is necessary any time there is an angle involved eg of real life trigs: bulding a house!!
ReplyDeletei enjoy 2D because it is less complicated than 3D
ReplyDelete3D trigs is more realistic triangles than 2D trigs
ReplyDeleteTrigs delas with the relationship between angles and sides of a triangle.
ReplyDeleteI have been exploring information about the swimming pool filtration plant for a long time now due to the project I am currently working on and so far perhaps this is the best website I have came across.
