Derivatives of Exponential Functions

The video tutorial explains how to find the derivative of a function using the product rule. It begins by introducing the concept of derivatives and the product rule, then applies the rule to a function involving exponential terms. The tutorial demonstrates how to find the derivative of each component and simplify the resulting expression. Finally, it shows how to factor out common terms to express the derivative in a simplified form.
