# Numerical Integration

This applet shows the visualization of 3 numerical integration techniques; Midpoint Rule, Trapezoid Rule, and Simpson's Rule. You can change the function, the number of divisions, and the limits of integration. To get the results for Simpson's Rule, the box must be checked. Simpson's rule takes a lot of processing, so be patient after checking the

*Simpson's Rule*box. Your browser may even indicate that the script has stopped, but it is working, just wait. If you have a relatively new computer, it should not be a problem. Once Simpson's rule is displayed, you can cycle through the parabolas that make up the estimate.Download our apps here:
