[tex] \sin x \cos x = \dfrac{\sqrt 3}{4}[/tex]
[tex] 2 \sin x \cos x = \dfrac{\sqrt 3}{2}[/tex]
[tex]\sin 2x = \sin \frac \pi 3[/tex]
[tex] 2x = \frac \pi 3 + 2 \pi n \textrm{ or } 2x = (\pi - \frac \pi 3) + 2 \pi n \quad \textrm{integer } n[/tex]
[tex] x = \frac \pi 6 + \pi n \textrm{ or } x = \frac \pi 3 + \pi n[/tex]
