## Numerical Integration

This applet demonstrates two numerical integration algorithms. It computes the area under a function's curve in the interval [2, 10] by using an increasing number of intervals.

## To run the demo:

- First define the function to integrate:
- Click the mouse in the graph panel to set from 2 up to 10 data points.
- Click the
**Plot integrand**button to plot the function through the points.

- Choose a numerical integration algorithm:
- Trapezoidal
- Simpson's Parabolic

- Click the
**Step**button repeatedly to compute the area under the curve with an increasing number of intervals. - At any time, choose the other integration algorithm for the
same function, or click the
**Reset**button to start over.
