Riemann Sums
As you've learned in class, we are often interested in finding the signed area under the graph of a function from to . We can approximate this area using left-hand and right-hand sums. This applet helps you to do just that.
To use: enter your function and endpoints of the interval in the boxes labeled f(x), a, and b, and then hit the "Update" button. (After you put something in a box, you may need to hit enter.)
