Answer
a) Need to caculate the value of a trigonometric funtion $tan$.
$tan^{-1}(-1)=(-\frac{\pi}{4})$
b) Need to caculate the value of a trigonometric funtion $tan$.
$tan^{-1}\sqrt 3=(\frac{\pi}{3})$
c) Need to caculate the value of a trigonometric funtion $tan$.
$tan^{-1}(\frac{-1}{\sqrt 3})=\frac{- \pi}{6}$
