2SinПи /6Минус корень 3 sin пи 3/ctg пи/4 tg пи /6

Answer 1

$2sin \frac{\pi}{6} - \sqrt{3} sin \frac{\pi}{3} ctg \frac{\pi}{4} tg \frac{\pi}{6} = \\ = 2 \times \frac{1}{2} - \sqrt{3} \times \frac{ \sqrt{3} }{2} \times 1 \times \frac{ \sqrt{3} }{3} = \\ = 1 - \frac{ \sqrt{3} }{2} = \frac{2 - \sqrt{3} }{2}$
