There is no differential equation solver included in SMath yet, but you can solve differential equations numerically. See the Example on 5-th order Runge-Kutta included in SMath Examples. Read Tutorials and Examples on SMath Wiki. See this post Areas and snippets and download this file RungeKutta5.sm and use it. Or, you can make your own program.

Thanks for reply. Numerically methods i writting himself in C++. I looking, for differential equations solver for my PDA, couse i can't write program for Windows Mobile. So i wait for included differential equation in Smath
