Ответ:

$\displaystyle ctg\Big(-\frac{\pi }{3}\, x\Big)=\sqrt3\\\\\\-\frac{\pi}{3}\, x=\frac{\pi}{6}+\pi n\ ,\ n\in Z\\\\x=-\frac{1}{2}-3n\ ,\ n\in Z\\\\\\\\P.S.\ \ ctg\Big(-\frac{\pi }{3}\, +x\Big)=\sqrt3\\\\\\-\frac{\pi}{3}+x=\frac{\pi}{6}+\pi n\ ,\ n\in Z\\\\x=\frac{\pi}{3}+\frac{\pi}{6}+\pi n\ ,\ n\in Z\\\\\\x=\frac{\pi}{2}+\pi n\ ,\ n\in Z$
