New issue 2296 by asmeurer: x*x.conjugate() should be recognized as real
http://code.google.com/p/sympy/issues/detail?id=2296
In [71]: (x*x.conjugate()).as_real_imag()
Out[71]:
⎛ ⎛ ⎽⎞ ⎛ ⎽⎞⎞
⎝re⎝x⋅x⎠, im⎝x⋅x⎠⎠
It should return something like (abs(x)**2, 0). At the very least, the
assumptions should recognize it as real, so im(x*x.conjugate()) should go
to 0.
