**1. Homework Statement**

Hi

I have a complex function of the form

[tex]

\frac{1}{1-Ae^{i(a+b)}}

[/tex]

I want to take the complex conjugate of this: The parameters

*a*and

*b*are complex functions themselves, but

*A*is real. Am I allowed to simply say

[tex]

\frac{1}{1-Ae^{-i(a^*+b^*)}}

[/tex]

where * denotes the c.c.? I seem to vaguely remember that [itex]f^*(x) = f(x^*)[/itex].
