I don't understand Part 2: using the fundamental theorem of calculus

Part 1: A derivative computation using the chain rule Suppose F(x) is any function that is differentiable for all real numbers x. Evaluate the following derivative. d dx (F(x*)) = 4x13F'(x^4) Enter the derivative of F(x) as F'(x) using prime notation. Your answer should be in terms of F' and other functions of the variable x. Part 2: A derivative computation using the FTC Suppose F(x) = e""" di. Use the Fundamental Theorem of Calculus to evaluate the derivative. F'(x) = d dx Part 3: A composition of two functions Part 4: A derivative computation using the FTC and the chain rule
