Evaluating the composition of Functions

The video tutorial explains how to find the composition of the sine of the inverse cosine of 1. It begins by discussing the concept of function composition and the importance of evaluating the innermost function first. The tutorial then demonstrates how to evaluate the inverse cosine of 1 by finding the angle Theta on the unit circle where the cosine equals -1, which is π. Finally, it evaluates the sine of π, concluding that the composition results in 0.
