Introduction
This program computes left, right, Trapezoid, Midpoint, and
Simpson's approximations for
.
If you have not used one of the programs posted on this website before,
you should read through
the information in the Intro to Programming
section first.

Running the Program
You will need to enter a function f(x) into
f1 before running
the program.
Store your function by hitting Fmem.
Store your equation in position 1. The program will ask for values of A, B, and N (number of
subdivisions).
To test the program try the following:
f(x) = x2+ 3,
A=1, B=4, N=20.
Your answer will be
L R T M S
28.88625
31.13625
30.01125
29.994375
