And I should note that Tom's code can also compute the Laplace transform if you want to do it that way: In [13]: var('s') Out[13]: s In [14]: inverse_laplace_transform(exp(-5*s)/s, s, t) Out[14]: Heaviside(t - 5) Aaron Meurer On Mon, Jan 9, 2012 at 1:36 PM, Aaron Meurer asmeu...@gmail.com

Thanks to Tom's Google Summer of Code project, SymPy can indeed solve this problem. The code is only in the git master, but will be included in SymPy 0.7.2. In [3]: dsolve(Derivative(y(x),x) - Heaviside(-5 + x), y(x)) Out[3]: ⎧ │x│ y(x) = C₁ + 5⋅⎪
