Homework Statement
Hello, I am supposed to express the and the phase part of expression:
[itex]\displaystyle{S=\frac{k}{\sqrt{1+i\gamma_0}} \cdot exp\left(\frac{z}{1 + i\gamma_0}\right)}[/itex]
Homework Equations
The answer should be in the form:
[itex]\displaystyle{S=a(\gamma_0) \cdot exp\left(i\varphi(\gamma_0)\right)}[/itex]
The Attempt at a Solution
Well, its clear(probably) that for the amplitude part I just have to multiply this equation by its complex conjugate and take a square root out of the result. This leaves me with the expression of:
[itex]\displaystyle{ a(\gamma_0)=\frac{k}{\left(1+\gamma^2_0\right)^{1/4}} \cdot exp\left(\frac{z}{1+\gamma^2_0}\right) }[/itex]
However, I don't quite understand how to get the complex(phase) part of the number? A hint where to start would be very gladly accepted :), thank you.
