Understanding Derivatives of Exponential Functions

The video tutorial explains how to determine the derivative of an exponential function using the chain rule. It begins by identifying the composite function and its inner function, then applies the chain rule to find the derivative. The process involves rewriting the function in terms of 'u' and calculating the derivative using the natural logarithm. The tutorial concludes with a simplified expression of the derivative and a preview of the next video, which will cover the product rule.
