\sin x\cdot\cos x-\frac{\sqrt[]{3}}{2}\cos x=0
\cos x(\sin x-\frac{\sqrt[]{3}}{2})=0
\begin{gathered} \cos x=0 \\ x=(\pi)/(2),(3\pi)/(2) \end{gathered}
\begin{gathered} \sin x-\frac{\sqrt[]{3}}{2}=0 \\ \sin x=\frac{\sqrt[]{3}}{2} \\ x=(\pi)/(3) \end{gathered}

so the answer is pi/2, 3pi/2, and pi/3
