New issue 1964 by reni...@gmail.com: as_real_imag for Piecewise does not
give correct answer
http://code.google.com/p/sympy/issues/detail?id=1964
For x a real Symbol
a = 2*I*(3*sin(4*x)-3*sin(4*x)*Piecewise((2.0, x<0), (1.0, 0 <= x)))
a.as_real_imag() =>
Re: -6*I(I*im(Piecewise(...))+re(Piecewise(...)))*sin(4*x)
Im: 6*sin(4*x)
It should be
Re: 6*sin(4*x)*im(Piecewise(...))
Im: -6*sin(4*x)*re(Piecewise(...))
I am using version 0.6.7 downloaded from the website on ubuntu 10.04 on
amd64 if that is important.
Regards,
Renier
