How to solve a riemann sum

WebFor example: Finding the upper, lower, left, right and midpoint sum of ∫ − 1 3 ( x 2 − x − 1) d x P = − 1, 0, 3 2, 3 First, I don't know what the graph of this function would look like so I've been driven to alternative ways of solving Riemann sums. WebThis is easy to compute: just sum the width times height. The sum that gives this area is known as a Riemann sum. Because the height is not constant over the little interval, there is no one correct height. You could certainly cover the targeted area with your rectangles by always 27 choosing the highest point in each interval.
