# Complex conjugate exponential watch

1. I'm struggling a little with complex conjugate for this exponential function that has two components in the exponential.

Im not sure weather the conjugate changes the sign of everything in the power or just the 'i' component?

Could someone clarify weather C1 or C2 is correct?
Thanks

Just the complex/i component. So C2 is.

For two complex numbers we have that and if is real, then . So in your case, we get:

assuming that is real.
