This applet shows three points on a curve separated in by . Straight dotted lines connect the points. Moving the blue dot will change the location. Moving the black dots will change the function. There are three check boxes.
- Trapezoids shows the areas that would be used for trapezoid numerical integration.
- Parabola shows a quadratic equation fit through the three points.
- Simpson's Rule shows the area that would be used for Simpson's rule integration.
