Comment #2 on issue 3099 by ronan.l...@gmail.com: Expr.is_constant() is
very slow in some cases
http://code.google.com/p/sympy/issues/detail?id=3099
The problem is that is_constant() does numerical evaluation, which happens
to be very slow in the case of test_expr.py::test_equals_factorial()
def test_equals_factorial():
assert factorial(x + 1).diff(x).equals(((x + 1)*factorial(x)).diff(x))
