Let us assume that \tan^{-1}(-\sqrt3) = x, then we have;

\tan x = (-\sqrt 3) or

 -\tan (\frac{\pi}{3}) = \tan \left ( \frac{-\pi}{3} \right ).

and as we know that the principal value of \tan^{-1} is \left ( \frac{-\pi}{2}, \frac{\pi}{2} \right ).

Hence the only principal value of \tan^{-1}(-\sqrt3) when x = \frac{-\pi}{3}.
