Euler's Method (basic)

Name:         Eulm: Eulerg, Eulert
Author:       Wilson W. Ng   Waesh@yahoo.com
Version:      1.1
Machine:      TI-82, TI-83, and TI-83plus
Released:     May 11, 2002
Description:  Numerical solution for differential equations. Table and graph option included.

------------
Instructions
------------
Eulerg and eulert are subroutines. Run Eulm as the main program and hit
enter at title screen.

For the 82, go to the graph menu and enter your equation

(Y1) enter your equation
(X) initial x-value
(Y) initial y-value
(H) step size

(N) number of points for table only


Example:
	dy/dy = -2xy^2 	f(-2) = 0.2

Enter -2X*Y^2 for (Y1)

-2 for (X)

0.2 for (Y)

0.1 for (H)

Then select graph or table.

40 for (N) table option only

------------
Version 1.1
------------
Fixed some bugs. 


--------------
Known Problems
--------------
There might be some minor problems with the program. This version was ported 
from my 86/85 without testing the program on the 82, 83, and 83 plus. However,
I looked through the texas instrument guidebooks in the programming section of
the 82 and 83plus. If you know a little about basic programming, you can probably
fix the I/O and Ctrl errors.
