WebOne part of solving this question initially boils down to finding all $\theta \in [0,2\pi]$ such that $\tan\theta=\frac{y}{x}=-\frac{\sqrt{2}}{\sqrt{2}}=-1.$ ... But for $\theta=\tan^{-1}(-1)$, we know $\theta$ can only be $-\pi/4$ if it is to be in the range of $\tan^{-1}$, and with $\tan\theta=-1$ there are infinitely many solutions, so how ...
