The older version of this answer seemed pretty good. I don't understand the edit... I also don't understand the addition of a second answer from the same user.
Pr A Find all solutions of the equation $\sin\theta=\cos\theta$.
Pr B Solve the equation $\sin\theta=\sqrt{3}\cos\theta$ for $0\le \theta <2\pi$.
Pr C Solve the equation $\sin 2\theta=\cos\theta$ for $0\le \theta <2\pi$.
Pr 1 Solve the equation $2\sin^2 \theta - \sin \theta =0$ for $0\le \theta
