What are the some applications of trigonometry?
Q. I know that trig is use mainly by surveyors, navigators, map makers,etc. But how can a person like me, who is not a scientist nor professional mathematician to use trigonometry in everyday lives?Please give me some examples of problems where can I use it.(for example in home) And please explain the solutions. I just want to know because I found trigonometry to be hard if I didn't know how to apply it.

A. You want to cut down a tree. Based on its shadow and elevation angle you can estimate its height and know where it might fall. I think that you might be limiting yourself. You might feel that if it cannot be used around the house, what is it good for. Many other things cannot be used around the house, cranes, operating tables, stop lights, wind generators, but a very useful to every day life. With out an understanding of trig, you would not get AC power to your house. You personally do not use it, but you are sure glad that the engineers generating the power and getting it to your house do,

What is the difference between geometry and trigonometry?
Q. This school year, I am going to take geometry and trigonometry at the same time. There would be a huge possibility that my teacher would ask this question. Besides, I don't understand anything.
Asked by anyamaddie - Wed Jun 4 12:02:35 2008 - - 5 Answers - 1 Comments

A. Having taught both topics, I don't think there should be a problem doing both at the same time providing that they are basic courses. Trigonometry is about working out the sizes of angles or the lengths of lines from one another. Geometry if more about whether angles and lengths are equal or not without actually working out their sizes. That's a very brief answer and so has possibly simplified it too much.

What is the correct version of the following Trigonometry formula?
Q. In Trigonometry there is a formula that reads: CosA - CosB = -2Sin((A+B)/2)Sin((A-B)/2 ). Unfortunately, I have two different textbooks that show this formula differently. Also, when I look it up on-line, several websites quote the formula differently as well! One variation, for example, is: CosA - CosB = -2Sin((A+B)/2)Cos((A-B)/2 ). Are all of these formulae interchangable, or is one of them correct and the rest incorrect? Thanks!
Asked by tangoprince - Wed Feb 28 13:54:43 2007 - - 5 Answers - 0 Comments

A. My handbook has: cosA - cosB = -2sin( (1/2)(A+B)) sin((1/2)(A-B)) You can check the textbooks by trying a few values. For example, try A= B = 45 degrees. The second formula in your question becomes: CosA - CosA = 0 = -2Sin(A) But ... this is not correct in general (it is correct only if A = 0, 180 degrees, 360 degrees, ...). So the second formula can not be correct for all angles. Are you sure you got all the parenthesis correct?

What is the best website for high school trigonometry help?
Q. This is a problem that I have been faced with for a long time now. I always need help with some parts of my trig work. The reason being is that my trig teacher won't even explain anything. He just starts my class on a new chapter after a test and lets us figure it out on our own. Not exactly too helpful, is it? So, what I want to know is what are some of the best websites for high school trigonometry help and or review. I would greatly appreciate anything you can think of.

Is it ok to take Physics (Calculus based) with a background of only College Algebra and Trigonometry?
Q. Hi guys, I just wanted to seek a little bit of your advice. I have not taken Pre-Calculus or Calculus before. But I have taken College Algebra and Trigonometry.

A. Depends on the difficulty of the University. If you're at MIT, University of Michigan, Virginia Tech or another top ranked science university then i would never go into a class under prepared. If it's in a community college there should be enough people that don't know what's going on anyway that you can get away with not knowing all of the calculus background for a calc based physics class

How much trigonometry is there in Calculus I?
Q. I will be finishing my pre-cal/trigonometry course this semester, so I was wondering what does Calc I consist of? Is it very difficult?
Asked by serge.coudert - Tue Nov 3 20:49:48 2009 - - 1 Answers - 0 Comments

A. I'd say that Calculus I is composed of about 15% trigonometry. The main ideas of calculus (limits, derivatives, integrals, and series) have nothing to do with trigonometry, but you apply these ideas to trigonometric functions for variety. You won't be responsible for knowing any trigonometric identities, but it helps to know your unit-circle because you'll be finding trigonometric roots pretty often. Trust me, most people don't like trigonometry. So don't let it stop you. Though, "Is Calculus I very difficult?" Like any math, I find that the difficulty is usually related pretty thoroughly to how much you study the concepts and how good your teacher / professor is. It might be easier to keep up with the concepts of Calculus I since… [cont.]

Q. How much geometry is need before I can learn trigonometry?
Asked by jack - Fri Jun 8 23:39:05 2007 - - 9 Answers - 0 Comments

A. You will not need a lot of geometry to go into trig. Trig is mainly the study of triangles, so all the formulas rules you know about angles and triangles from geometry should be somewhat familiar in your mind. You will be introduced to a few new topics like the trig functions of Sine, Cosine, and tangent, along with the Law of Sines and Law of Cosines. If you know most of the basics from Geometry and above average memory of triangles, youll do fine in Trig especially if you have a good teacher who can explain the new topics while refrshing the old geometry topics.

What is the difference between Pythagoras & Trigonometry?
Q. How can you tell the difference between a Pythagoras Theorem and Trigonometry question in a Mathematics Paper, without it telling you which method to use?
Asked by G.W.K - Sat Nov 15 12:05:37 2008 - - 7 Answers - 0 Comments

A. It is best to use the Pythagoras theorem when you have been given a minimum of two sides, and the question requires you to find the other length. Also the Pythagoras theorem is based on a right-angled triangle. If the question requires you to find an angle, or find the length of a side given an angle, then use Trigonometric theorems. Hope this helps.

A. Trigonometry is defined for non right angled angles but the rules are different. Trig ratios are only defined for right angled triangles because in non right angled triangles, there is no hypoteneuse because there is no side opposite a right angle.
