This applet give the user an opportunity to practice finding limits of integration in double integrals. The user can enter the limits and the resulting region on the plane is displayed. In many practice problems that are provided, the region is given and suitable limits of integration in Cartesian or in polar coordinates are supposed to be found.

Note:   The complete source code for the first version (the AS3 version) is available in the article "Visualizing Regions for Double Integrals" that you can find at Custom Classes for Mathematics section of Flash and Math.
