4g Example 3 (Composition of Inverse Trig with right Triangles)

The video tutorial explains how to evaluate trigonometric compositions when values are not on the unit circle. It emphasizes using triangles to understand trigonometric functions like sine, cosine, and tangent. The tutorial covers solving problems using inverse functions and handling negative values. It also explores abstract concepts involving unknowns, using algebraic expressions to represent trigonometric relationships.

What is the importance of showing work when solving trigonometric problems?

How can you represent the tangent of an angle in terms of the sides of a triangle?

What is the process for finding the sine of an angle when the cosine is known?

Describe how to handle values that are not on the unit circle when solving trigonometric problems.
