Объяснение:

$cos( \frac{x}{3} - \frac{\pi}{6} ) = \frac{ \sqrt{2} }{2} \\ \frac{x}{3} - \frac{\pi}{6} = - + arccos \frac{ \sqrt{2} }{2} + 2\pi \: n$

$\frac{x}{3} - \frac{\pi}{6} = - + \frac{\pi}{4} + 2\pi \: n \\ \frac{x}{3} = - + \frac{\pi}{4} + \frac{\pi}{6} + 2\pi \: n \: | \times 3 \\ x = - + \frac{3\pi}{4} + \frac{\pi}{2} + 6\pi \: n$
