Epsilon-Delta:  Optimum Delta Finder
Author:  Brandon Cox  <brandonc4x4@yahoo.com>
Calcs supported:  TI-83/TI-83+
Installation:  Send it to your calculator with a TI graphlink or other compatible link cable.
Use:  To find the optimum delta for a given limit and epsilon.  Shows the epsilon band and delta band graphically, and then shows just the box with the line (hopefully) going through one corner of the screen and out the other, proving that the delta is indeed optimum.

Instructions:  Input the function (f(x)), the epsilon value, the limit, and the a value.  Your reward will be an optimum delta.  Remember this--because of the limitations of the 83 calculator, there is no efficient way for it check the validity of you limit.  So do all the checking beforehand.

Please give me feed back if anyone feels this program needs something or if something is inaccurate or incorrect.

Don't cheat--unless you have too.
