I am trying to calculate things like $z/(e^z-1)$, or find the inverse of $x=z+ 2z+5z^2+\cdots$, expand as power series. What is the best (or favorite) software package you use to do stuff like this?</p> <p>Thanks in advance!</p> http://mathoverflow.net/questions/111400/good-computer-package-for-calculating-inverse-of-a-formal-power-series/130265#130265 Answer by Nick Orbeck for Good Computer Package for Calculating Inverse of a Formal Power Series?
