TI-92 Program:  RECTANGL

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, type in rectangl()
2. work your way across the menu, store the function f(x)-
   F1, set the Bounds-F2, set the number of intervals N-
   F3, set the Graph Window-F4, select Method-F5.
   Use the down arrow to move between fields when entering
   information.
3. Select the method: Left-hand sums-F1, Midpoint sums-
   F2, Right-hand sums-F3, Trapezoid rule-F4, Simpson's
   rule-F5.
4. Use ENTER to see the value of the sum.



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