Comment #3 on issue 2955 by smi...@gmail.com: Function to compute the domain of a function
http://code.google.com/p/sympy/issues/detail?id=2955
FWIW, there is the denoms function in solvers that can help with this (I wrote this earlier today but can't seem to locate it now):
>>> eq=(1+1/x)/(x-1) >>> from sympy.solvers.solvers import denoms >>> exclude = set() >>> for d in denoms(eq): ... for s in solve(d): ... exclude.add(s) ... >>> print exclude set([1, 0]) -- You received this message because you are subscribed to the Google Groups "sympy-issues" group.
