The solution set of the inequality

tg x \leq \frac{\sqrt{3}}{3}

for

x \in R

is:

⋃_{k \in Z} (- \frac{π}{2} + k π; \frac{π}{6} + k π]

⋃_{k \in Z} (\frac{π}{6} + k π; \frac{π}{3} + k π)

⋃_{k \in Z} (- \frac{π}{2} + 2 k π; \frac{π}{6} + 2 k π]

⋃_{k \in Z} (\frac{π}{6} + 2 k π; \frac{π}{3} + 2 k π)
