Comment (by rws):
Replying to [comment:9 kalvotom]:
> I have doctested the function with git version of Sympy and all tests
passed (especially the one with integration). I guess we have to wait for
a new version of Sympy to arrive in Sage (probably Sympy 0.7.7).
Yes, other tickes are waiting for that too.
> Anyway, this is my first attempt to contribute to Sage, so feel free to
knitpick.
Will get to it.
> I have one question. How complicated it would be to force Sage to
perform simplifications like
> {{{
> sage: exp_polar(2 + 5*I)*exp_polar(5 - I)
> exp_polar(7 + 4*I)
> }}}
> My current understanding is that such simplifications are taken care of
by an external library ( Pynac ) and there is no way how to do this in
Sage alone, am I right?
I think so, but I'm not much into Pynac. Anyway, it could be part of
Python Sage by including a function that does it in one of the
`Expression.simplify*` methods.
