## Main Question or Discussion Point

Hi,

I'm currently doing some work with black holes and I need a powerful graphing tool.

Are there any free, downloadable graphing programs that can graph polar coordinates without having to make r(t) = ...?

I have some irreducable functions I need to view.

Thanks!
