This program will graph the slope field (direction field) and the integral curves of

where

and where $F(x,y)$ and $G(x,y)$ may contain parameters a, b, and c.

This program may be freely distributed by any means, including the web, provided that there is no fee or charge or consideration of any kind which is in excess of $8.  However, we retain all the rights of the program.

This is an alpha version of Slopes. It has received very limited field testing. It should run on Windows 98, Me, and XP, although not all these platforms have been tested rigorously. Please send any bug-reports, or suggestions, to David Lovelock at dsl@math.arizona.edu. Thank you.
