I need help with this practice It can be more than one answer, as stated in the instructions

we have the equation
[tex]\begin{gathered} 3\cot \theta=-\sqrt[]{3} \\ \cot \theta=-\frac{\sqrt[]{3}}{3} \end{gathered}[/tex]The solution for angle theta is
[tex]\theta=\frac{1}{3}\lbrack3\pi\cdot n-\pi\rbrack[/tex]simplify
[tex]\theta=n\pi-\frac{\pi}{3}[/tex]where
n ∈ Z
