For z3=3e^(-ipie/4) where does the function intercept the imaginary axis and what is the modulus?

I don't understand how this is supposed to be a function. What is your independent variable..? z..? z3..? z^3..?

[Ry122]

sorry just let z3=z

Recall Euler's formula for that one.

Still, z=3e^{-i\pi \frac{e}{4}} is not a function but some fixed constant number.
