Answer 2

$\huge\underline\bold\red{★Answer★}$

$let \: \: \: y = {cot}^{ - 1} ( \frac{ - 1}{ \sqrt{3} } ) \\ \implies coty = \frac{ - 1}{ \sqrt{3} } \\ \implies coty = - cot( \frac{\pi}{3} ) \\ \implies coty = cot(\pi - \frac{\pi}{3} ) \\ \implies coty = cot \frac{2\pi}{3} \\ \implies y = \frac{2\pi}{3} \\ since \: \: the \: \: principal \: \: brunch \: \: of \: cot ^{ - 1} is \: \: (0 \: \: \pi) \\ hence \: \: pricipal \: value \: is \: \frac{2\pi}{3}$
