Question:
I am having a hard time trying to figure out how to raise
the imaginary unit i to the imaginary power i.
In other words: i^i = ?
Where can I find more information on complex forms of Ln?

Replies:
Raising complex numbers to powers is often simplified by using Euler's
Formula:
exp(i*x) = cos(x) +i*sin(x)
You see for example, that for x=pi this becomes exp(i*pi) = -1 since
sin(pi)=0.

Similarly, exp(i * pi/2) = i, since cos(pi/2) = 0 and sin(pi/2) = 1
