Comment #2 on issue 2672 by asmeurer: UnificationFailed with integrate(-diff(y/(x**2 + y**2), y), x)
http://code.google.com/p/sympy/issues/detail?id=2672
Also, if you first simplify the input expression it works. In [13]: integrate(-diff(y/(x**2 + y**2), y).factor(), x) Out[13]: x ─────── 2 2 x + y So the problem is somewhere in the ratint() preprocessing. -- You received this message because you are subscribed to the Google Groups "sympy-issues" group.
