Evaluate the inverse trig function in composition

The video tutorial explains the process of solving a composition of functions by working from the inside out. It focuses on understanding the sine inverse function, particularly when the sine is negative, and the restrictions on angles in different quadrants. The tutorial then moves on to calculating the tangent of an angle, including rationalizing the denominator. The instructor emphasizes the importance of practice and understanding these concepts through multiple examples.

How do you find the tangent of an angle using its sine and cosine values?

What is the process to rationalize the denominator when multiplying by the reciprocal?
