This mathlet is used to facilitate understanding of integration by illustrating approximations to the integral. It computes sums using rectangles determined by left hand end points, right hand end points, and midpoints, as well as trapezoids. There is a choice of nine different functions. The user can choose the number of subintervals into which the interval is divided. Instructions on how to use the applet are included on the page.
