Use part one of the fundamental theorem of calculus to find the derivative of the function.
Step 1 :Given the function
Step 2 :We are asked to find the derivative of this function
Step 3 :According to the Fundamental Theorem of Calculus, the derivative of this function
Step 4 :So, we need to replace t with x in the function inside the integral to get the derivative of
Step 5 :Substituting
Step 6 :
