Make a small change to your answer in part (a) so that the sum will find the area using right-endpoint rectangles.
-values should you start and stop with?
Make a small change to your answer in part (a) so that the sum will find the area using midpoint rectangles.
Change the inside function to:
so that it is starting at the middle of each rectangle.
