*******Bisection method********
*******http://www.antaki.ca**********

Installing the program:
======================
Simply transfer the following files: bisection.89p to your calculator.(TI-89, TI-92 Plus or Voyage 200)
To run the program,type:"bissect()" on the home screen.

Requirements:
============
AMS 2.09 is preferred for this program. Tested only on AMS 2.09. The program may work on older AMS

Example:
=======
Finding the roots of x^2+sin(x)-exp(x), the root is between 0 and 2, so 0 is the lower bound and 2 is the upper bound, let's take an error on x equal to 10^-4, and the error on f(x) equal to 10^-4.
After 15 iterations we find the solution x = 1.99993896484
The exact digits are the four digits after the decimal point.


Notes:
=====
Thanks for using my program.
