Product rule and double chain rule with trig

The video tutorial covers the application of product and chain rules in calculus, focusing on understanding parent and child functions. It explains how to take derivatives of complex functions by breaking them down into simpler parts and applying the rules systematically. The tutorial includes examples and practice problems to reinforce the concepts, followed by steps to simplify the resulting expressions. The session concludes with a summary of the key points and additional practice suggestions.
