как найти ctg(-2*pi/3) или sin(2*pi/3)?

Answers & Comments

DimaPuchkov $ctg(-\frac{2 \pi}{3})=-ctg(\frac{2 \pi}{3})=-ctg(\pi - \frac{\pi}{3})=-(-ctg (\frac{\pi}{3}))=ctg (\frac{\pi}{3})=\frac{\sqrt{3}}{3} \\ \\ \sin (\frac{2 \pi}{3})= \sin (\pi - \frac{\pi}{3})=\sin (\frac{\pi}{3})=\frac{\sqrt{3}}{2}$
