Answer 1

Ответ:

$4 \cos(3 \times \frac{\pi}{6} - \frac{\pi}{6} ) + \tan( \frac{\pi}{6} + \ \frac{\pi}{6} ) = 4 \cos( \frac{\pi}{3} ) + \tan( \frac{\pi}{3} ) = 4 \times \frac{1}{2} + \sqrt{3} = 2 + \sqrt{3}$

Answer 2

$4 \cos( \frac{3\pi}{6} - \frac{\pi}{6} ) + \tan( \frac{\pi}{6} + \frac{\pi}{6} ) \\ 4 \cos( \frac{\pi}{3} ) + \tan( \frac{\pi}{3} ) \\ 2 + \sqrt{3}$
