TI-92 Program:  DEPLOT

This program will allow plot a direction field or slope
field for a given first order linear differential
equation.

1. To run the program, type in deplot().
2. Work your way across the menu, enter the differential
   equation-F1, set the graph window-F2, draw the slope
   fields-F3.  Use the down arrow to move between fields
   when entering information.
3. Press ENTER to return to the menu.
4. To view the rest of the menu use F4.  You can return to
   the previous menu-F1, you can display slope field again-
   F2, or use Eulers method-F3.
5. For Euler's method you will need to set the initial
   condition-F1, the increment-F2, plot the solution
   using Euler's method-F3 or select more options-F4
6. You can return to the previous menu-F1, display the
   slope field and the plot of the solution by Euler's
   method, approximate a value using Euler's method or 
   select more options.
7. To approximate a value by Euler's method enter the 
   final value for x-F1, the increment-F2, and the find
   the y value-F3.

Return will allow you to go back to the previous menu, 
Exit will quit the program.
