[sympy] state of SymPy

2011-01-04 Thread Sebastian Haase
Hi all, hi Ondrej, hi Aaron ! I am still not using sympy for anything yet, but I'm following the list and sympy's development in general with great interest. Just recently a friend of mine started having to do some differential equations for her PhD thesis and got (back) into using Mathematica for

Hi! This is an interesting question. I think it will take the whole community to answer it, because there isn't anybody who knows everything of what SymPy can do in every category. Rather, there are those who are up to date with the quantum stuff, those who do a lot with the polys and simplif

Thanks for the extensive answer. My friend is doing symbolic analysis so far. Maybe one more question: Who here on the list is using others CASs besides sympy and how often ? IOW, to what fraction of CAS tasks is SymPy already sufficient ? (as seen by the people who tend to use and like it) (Do

Well, I always double check my results in Maple when I am programming in SymPy (obviously). There are some cases where I double check the results, but there are many cases where I have come to trust the SymPy algorithms to be correct (especially trivial ones like diff(), but even in my risch_in
