$x = + \frac{\pi}{18} + \frac{\pi \: n}{3}$

Пошаговое объяснение:

$sin5x \times sinx - cos5x \times cos = \frac{1}{2} \\ cos(5x + x) = \frac{1}{2} \\ cos6x = \frac{1}{2} \\ 6x = - + arccos \frac{1}{2} + 2\pi \: n$

n€Z, знак € читать "принадлежит"

$6x = - + \frac{\pi}{3} + 2\pi \: n | \div \: 6 \\ x = - + \frac{\pi}{18} + \frac{\pi \: n}{3}$
