TI-85 Program:  INTEGRAT

This program will approximate the area of the region
bounded by the x-axis, the curve y = f(x), x = a, and
x = b using left-hand sums, right-hand sums, midpoint 
sums, trapezoid rule or Simpson's rule.  You can view
the results both graphically and numerically or 
numerically only.


1. Run the program, work your way across the menu, 
   store the function ( f(x) ), set the viewing window
   (Range), view the graph (Graph), select a method 
   (Method).
2. Select the method: rectangles (RECTA), trapezoids 
   (TRAPE), Simpsons rule (SIMPS), numerical 
   integration (NUMIN).  This option calls the programs
   RECTANGL, TRAPEZOI, SIMPSON, or NUMINT respectively.
3. Follow the instructions for the corresponding program.


Return will allow you to go back to the previous menu, 
Exit will quit the program.
