And yes, that step is valid, but the next step is illegal, the correct step would be something like:
-pi = pi + 2*n*pi

It depends on how you define logarithm. I could define ln for a complex number z to be:Quote:

Then e^ln(z) = z for all complex numbers z
I guess that could be one definition.

Nifty... Makes sense. :)
