TI-82 Program:  NUMINTG

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 and Simpson's rule.  You can view
the results numerically only.

1. Before you run the program, store f(x) in y1.
2. Run the program, respond yes to question if you did
   step 1, otherwise no and do step 1.
3. Work your way down the menu, set the bounds (BOUNDS), 
   the number of intervals (N), calculate the sums (SUM).
4. Press ENTER to see the rest of the sums, ENTER again
   to return to the menu.


Exit will quit the program.
