comment Choosing the branch of a logarithm
@joriki: yes I meant $-i\pi/3$, thanks for that. I thought a branch cut could be chosen arbitrarily, as long as it starts from a branch point (the origin in this case)?

Same result, Mathematica seems unaware that $(-1)^{1/5}$ is a complex number... Although Im[(-1)^(1/5)] seems all right...

Offtopic: does the \bar command result in ugly output? In my Firefox it displays waaay to high above, mmucking with every line containing such a symbol.

That's what I thought to have remembered from my course Complex Analysis. Thanks
