Vedclass · Answer

(B) We know that $\sin ^{-1}\left(\frac{1}{2}\right) = \frac{\pi}{6}$ (or $30^{\circ}$).We know that $\cos ^{-1}\left(\frac{\sqrt{3}}{2}\right) = \frac{\pi}{6}$ (or $30^{\circ}$).We know that $\cot ^{-1}\left(-\frac{1}{\sqrt{3}}\right) = \pi - \cot ^{-1}\left(\frac{1}{\sqrt{3}}\right) = \pi - \frac{\pi}{3} = \frac{2\pi}{3}$ (or $120^{\circ}$).Adding these values together:$\frac{\pi}{6} + \frac{\pi}{6} + \frac{2\pi}{3} = \frac{2\pi}{6} + \frac{2\pi}{3} = \frac{\pi}{3} + \frac{2\pi}{3} = \frac{3\pi}{3} = \pi$.

$\sin ^{-1}\left(\frac{1}{2}\right)+\cos ^{-1}\left(\frac{\sqrt{3}}{2}\right)+\cot ^{-1}\left(-\frac{1}{\sqrt{3}}\right)=$
