Homework Statement
Solve for theta:
Re { (1+j) ejθ} = -1
Homework Equations
euler's formula?
ejθ = cosθ + jsinθ
The Attempt at a Solution
(1+j) ejθ =ejθ+ Jejθ = cosθ+jsinθ +j(cosθ+jsinθ)
=cosθ+jsinθ+jcosθ+j2sinθ = cosθ-sinθ+j(cosθ+sinθ)
The real part equals -1 => cosθ-sinθ = -1
I don't think I'm supposed to find an angle that this is true... - Have i taken a wrong turn somewhere?
