Estimating Area Under Curves

Click the check boxes to turn on the actual area, or an approximation using rectangles or trapezoids. You can also drag the locations of points A and B to change the area.

Approximations of Area

This applet goes with our Chapter 4 Day 3 exploration of Riemann Sums.

To enter a different function, simply type "f(x)=" and then the function in the INPUT BAR.
