Explore Riemann Sums
Explore Rieman Sums
This applet facilitates exploration of Riemann sums. Enter the desired function in the f(x) box, left end and right endpoints. Number of rectangles may be selected using slider. To explore randomly selected partition points of the interval [left, right] click on the button to update the selection. Arbitrary checkbox works only if all others are unchecked.
