Riemann Sum Estimate. It may also be used to define the integration operation. Left endpoints right endpoints midpoints and trapezoids.
The riemann sum is only an approximation to the actual area underneath the graph of f. An integral defined in an interval a b gives us the value of the area enclosed between a function f x and the x axis in an interval a b as long as the function is continuous. Left and right riemann sums to make a riemann sum we must choose how we re going to make our rectangles.
Sometimes they are larger than the exact area this is called overestimation and sometimes they are smaller this is called underestimation.
