An equation is solved graphically as shown in the picture. The solution is marked in red. Choose the corresponding equation.
\[ \mathrm{tg}\,{x} = \frac{\sqrt{3}}{3} \]
\[ x \in ( -\pi ;\pi)\]
\[ \mathrm{tg}\,{x} = \frac{\sqrt{3}}{2} \]
\[ x \in (-\pi ;\pi )\]
\[ \mathrm{cotg}\,{x} = \frac{\sqrt{3}}{2} \]
\[ x \in ( -\pi ;\pi)\]
\[ \mathrm{cotg}\,{x} = \frac{\sqrt{3}}{3} \]
\[ x \in ( -\pi ;\pi)\]
