Kopie vanRiemann Sums
- Bert Bollen, J Mulholland
To approximate the area under a graph we split the region up into many thin rectangles. Drag the slider labeled n to increase the number of rectangles used. The height of the approximating rectangle can be taken to be the height of the left endpoint, the height of the right endpoint, or the height of any point in the subinterval. Drag the slider labeled "position" to change the point used for the height of the rectangle. The sum of the areas of all the thin rectangles is the Riemann Sum displayed. If you wish to change the function f, say to sin(x), then just type f(x)=sin(x) in the input field at the bottom of the applet.
