	This apLet is purely for fun! It uses the INT( ) function on the calculator to produce graphs that look like Christmas Trees.
	The idea is that you could give the apLet to a group of extension students and encourage them to produce trees of their own.

Curve Areas

This apLet allows the user to find approximations to the area under a curve by finding either the lower rectangular area, the upper rectangular area, or the trapezoidal area (Simpson's Rule).
The user can choose the end points of the interval, the type of calculation and the number of rectangles to be used. The rectangles (trapezoids) are drawn on the screen and the user is presented with the solution at the end of the illustration.
