The video tutorial explains how to find the derivative of a composite function using the chain rule. It begins by introducing the function f(x) = 2 * arctan(sin(2x)) and identifies it as a composite function. The tutorial then breaks down the process of finding the derivative by first identifying the inner function and its derivative. It uses the chain rule to calculate the derivative of the entire function and simplifies the expression. Finally, it provides guidance on how to enter the solution into an online homework system.
