diff equation grapher

[Rickertsen2]

Does anybody know of a free program for windows or linux that can graph differential equations TI-89 style? It needs to be able to generate images.

It's not free but, Mathcad has a student version that runs about 129$ including shipping. Just bought a copy for my son for Christmas. You can always beat yourself up and use excel and it's built in graphing.

Have you tried this program?

WZGrapher can also be used to graph numerical solution curves of integrals, to solve numerically and graph ordinary differential equations up to the fifth order, and to calculate value tables (also of ODEs) including the first derivative values.

Thats kinda works. I really need something that can do systems of differential equations. I would solve them to a single equation if i knew how :(

I really like that tool though
