In this resource, you can enter/modify any of the following parameters: f = greater function g = lesser function a = lower limit of integration b = upper limit of integration n = number of differential rectangles. Width of each rectangle = . To explore this resource in Augmented Reality, see the directions below the first screencast.

1) Open up GeoGebra 3D app on your device. 2) Go to the menu (upper left). Select OPEN. Under SEARCH, type fy3c4pyf 3) The slider controls the angle. a and b control the upper and lower limits of integration. The colored filling sliders are also there. To change the function (even though it's labeled "f"), change function h. n = number of discs.
