defint was written by wnc@datatamers.com to help figure out the definite

integral for a function using the reiman, simpsons, trapezoid, methods.





This program finds the definite integral in many ways, and has lots of

features. when u start it, it will as for f(x), input and equation, the

lower limit, the upper limit, and how many subintegers. A menu will

appear w/ trap ( for the trapezoidal method) reimn (for the reiman

method) Simps (for simpsons method) Cald (for the calculator's value)

Menu 2 (for the next menu). In the next menu you can choose Shade, for

drawing the graph w/ shading the integral, ALL which shows all the

methods at once (useful), Menu1 to goto the first menu, and quit.

2 sub menus to know about: in shade, you will be prompted to the size of

the graph window, eg min. x max c min y max y values. and the Reiman sum

will allow you to choose between the left, mid, and right reiman sums.
