Calculator test

\[2k\pi i\
\[\ln(re^{i\theta}) = \ln r + i\theta + 2k\pi i\]

I'm sorry, but I don't understand wikipedia's interpretation of k, it seems to be quantized?

The equation, I have shown, is from a pure math prospective, for example assume z=1+2i

Entering this on my ti84+ reveals the answer of 0.8+1.11i

If I calculate this using the equation given, then on my ti30x pro, I get 0.8+1.11i
Doing the same calculation on the hp 35s reveals the same answer. I think you are mixing up pure maths with applied math/physics?I have not specified what the imaginary part actually is physically.
