Riemann Sums

Use Reimann sums to approximate the area under the curve. Enter the function you want to examine into the box labled f(x)=. Then choose your endpoints using the sliders labeled a and b. You can also adjust the number of rectangles using the slider labeled n.

This is a Java Applet created using GeoGebra from www.geogebra.org - it looks like you don't have Java installed, please go to www.java.com

1. How did the upper and lower sums compare?

2. What happens when you increase the number of divisions (n)?

3. Do you agree that these approximations could be useful?
