I am taking a Calculus class and we are studying Reimann Sum. I am trying to plot a function with the boxes drawn in at the right endpoints, left endpoints, and middle points. For example, f(x)=x^2, find the area under the curve on the interval [0,3], n=10, with a) right endpoints, b) left endpoints, and c) middle points. I can do it mathematically but I can not plot it yet. I have searched through the tutorial online, but can't seem to find anyway to do it. Any help is appreciated. Thanks.
