Ch 4 project How to solve problems with trigonometry

In Ch. 4 we learned about the 6 trigonometric functions. They arose from ratios formed within a right triangle. There's sine, cosine, tangent, cosecant, secant, and cotangent. We could use these functions to find missing angles, height, distance, length, and even the hypotenuse. The type of problem I made up was an indirect measurement. I solved the problem by using the trigonometric functions I learned from Ch. 4.

Chapter 4 Project: solving Word Problems with Trigonometry

In Chapter 4 we learned about the six trig functions:

1. opposite/hypotenuse=sine
2. adjacent/hypotenuse=cosine
3. opposite/adjacent=tangent
4. hypotenuse/opposite=cosecant
5. hypotenuse/adjacent=secant
6. adjacent/opposite=cotangent

You can use an angle measure to determine a missing site of your triangle. For example if you have 12ft length and an angle that is 30 degrees and the 12ft is opposite from the andgle and x is adjacent to the angle you can use tan(30)=12/x to find x. We also learned how to use the Unit Circle to find the measure of sides of triangles by using the 45-45-90 and 30-60-90 triangles.We use trig functions when working out word problems dealing with angles of depression which is when you look down and angles of elevations when you look up. You can also solve inderect mesure which is the word problem I made up using the angles odd depression.
