[sage-support] Programming animation

Hiya! Is there a relatively simple way to get a point to animate a point through a cycle keeping in mind my low programming skills ((like adding a wait between iterations?) ? I made this video with stop animation and an animated gif but it was a real pain.

[sage-support] Numerical approximation of symbolic coefficients

I've got these polynomials in two variables, `x`, and `u`. The polynomials are low degree (eight at the moment), but I'm working symbolically, so they print exactly: ..+ 314069483520)*sqrt(3) - 80295755776*x + 4831838208)/(1953125*x^63 - 73828125*x^61... All I would really like is to

Re: [sage-support] Numerical approximation of symbolic coefficients

First attempt: loop through each term and try to n() the coefficient. Madness. Based on a suggestion Mike Hansen once gave me -- http://ask.sagemath.org/question/411/substituting-expressions-for-numbers -- I tend to use subclasses of Converter when I need to do something like this, so as not to
