The solution set of the inequality \( \mathrm{tg}\, x \leq \frac{\sqrt3}3 \) for \( x\in\mathbb{R} \) is:
\( \bigcup\limits_{k\in\mathbb{Z}}\left(-\frac{\pi}2+k\pi;\ \frac{\pi}6+k\pi\right] \)
\( \bigcup\limits_{k\in\mathbb{Z}}\left(\frac{\pi}6+k\pi;\ \frac{\pi}3+k\pi\right) \)
\( \bigcup\limits_{k\in\mathbb{Z}}\left(-\frac{\pi}2+2k\pi;\ \frac{\pi}6+2k\pi\right] \)
\( \bigcup\limits_{k\in\mathbb{Z}}\left(\frac{\pi}6+2k\pi;\ \frac{\pi}3+2k\pi\right) \)
