New issue 3920 by t.hi...@gmail.com: Derivative wrt to the real or imag
part of a complex number
http://code.google.com/p/sympy/issues/detail?id=3920
I would expect the output of
r = symbols('r', complex=True)
diff(r, re(r))
to be 1. However, 'diff' returns 0.
If I write r as x+I*y, which I would like to avoid, then diff(r,x) works as
expected.
