Casio fx-7500G programs - Integral v.1.0

This program calculates the finite integral defined on a R->R function and an interval.

Commands and input

First of all, you have to define the function f(M) in a separate program; the number of program will be the same as in the "PROG #N#" line (look at the program source below). Here is an example:

For function 3x^2+4, save this program:
3M^2 + 4 -> O (the "O" letter, not the "0" number)

Other requested inputs will be A and B, the left and right interval limits, and D, the number of divisions of this interval. Higher values of D will give a more precise result but will take more time to calculate.
