I was just browsing SAGE a few days ago and wasn't able to find a differential equations solver. I don't care about an explicit formula for the solution, but rather a solver that in particular can create nice graphical output of the trajectories. 2D is essential, but even better if it can do 3D as well, allowing rotations of space for viewing the trajectories. Anyone know of such a thing? (I believe Cornell used to allow free downloading of their dynamical systems software, unfortunately named DSTools, which could do these things. But its website seems dead.) --Dan On 2013-05-08, at 6:31 AM, Cordwell, William R wrote:

Maple has a student edition, identical to the professional edition, for $99, must provide proof you're a student. Sage is free.
