Learn how to find the composition of cosine and sine inverse

The video tutorial explains how to solve composition problems by focusing on the innermost function first. It uses the example of finding the angle for sine inverse of 1/2, highlighting the importance of understanding the unit circle and the restrictions of the sine inverse function. The tutorial also covers calculating the cosine of an angle and encourages practicing with calculators to reinforce learning.
