Understanding Derivatives and Integrals

The video tutorial explains how to take the derivative of an expression using the fundamental theorem of calculus. It discusses the scenario where x appears on both the upper and lower boundaries of a definite integral. The tutorial demonstrates how to graph the function, break the integral into two parts using a constant, and apply the chain rule to solve it. Finally, it simplifies the expression to find the derivative.

What is the main challenge in finding the derivative of the given expression?

• The function is not differentiable.
