Understanding Derivatives and Related Rates

The video tutorial covers the application of derivatives, specifically the chain rule, to solve practical problems. It begins with a review of the chain rule, followed by a geometric problem involving the volume of a cone. The tutorial then applies calculus to determine the rate at which the water level in a cone rises as water is poured in. The explanation includes step-by-step calculations and emphasizes understanding the chain rule in different notations.

What is the chain rule used for in calculus?
