The solution set of the inequality \( |\mathrm{cotg} x |\leq \sqrt3 \) for \( x\in\mathbb{R} \) is:
\( \bigcup\limits_{k\in\mathbb{Z}}\left[\frac{\pi}6+k\pi;\frac{5\pi}6+k\pi\right] \)
\( \bigcup\limits_{k\in\mathbb{Z}}\left[\frac{\pi}6+k\pi;\frac{\pi}2+k\pi\right] \)
\( \bigcup\limits_{k\in\mathbb{Z}}\left[\frac{\pi}2+k\pi;\frac{5\pi}6+k\pi\right] \)
\( \bigcup\limits_{k\in\mathbb{Z}}\left[ k\pi;(k+1)\pi\right] \)
