, for instance. A human isn't going to run through the full Euclidean algorithm to compute gcd(1, x), for instance, and even for gcd(x, x**2 + x) a human can see the answer right away without running through any polynomial long division. Aaron Meurer On Wed, Oct 29, 2014 at 3:40 AM, Christophe Bal

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
