The Attempt at a Solution
I attempted to use the formula zj = xj + iyj to substitute both z's. Further simplification gave me (x1 + x2)cosθ + (y2 - y1)sinθ or, Re(z2 + z1)cosθ + Im(z2 - z1)sinθ.
Is this a valid answer? Or are there any other identities I should have used to obtain an answer purely in 'z'?
I don't seem to be able to reduce the problem into Acosθ + Bcosθ any other way.
Thanks in advance!
