I noticed some bugs that are caused because SymPy is not sure of sign of some variable. Look at this issue for example:- http://code.google.com/p/sympy/issues/detail?id=4030&q=label%3ASeries&colspec=ID%20Type%20Status%20Priority%20Milestone%20Reporter%20Summary%20Stars
When I try series(x**y, x) then, if y is positive it returns an answer but when not it just returns O(log(x)**6). In such cases should SymPy just assume that other variables are positive as well? x variable is always substituted by a dummy x that is assumed to be positive. -- You received this message because you are subscribed to the Google Groups "sympy" group.
