(C) ધારો કે $x = 	an ^{-1}\left(\frac{1+\sqrt{3}}{3+\sqrt{3}}ight)$.દલીલનું સાદું રૂપ આપતા: $\frac{1+\sqrt{3}}{\sqrt{3}(\sqrt{3}+1)} = \frac{1}{\sqrt{3}}$.તેથી,$x = 	an ^{-1}\left(\frac{1}{\sqrt{3}}ight) = \frac{\pi}{6}$.ધારો કે $y = \sec ^{-1}\left(\sqrt{\frac{8+4 \sqrt{3}}{6+3 \sqrt{3}}}ight)$.દલીલનું સાદું રૂપ આપતા: $\sqrt{\frac{4(2+\sqrt{3})}{3(2+\sqrt{3})}} = \sqrt{\frac{4}{3}} = \frac{2}{\sqrt{3}}$.તેથી,$y = \sec ^{-1}\left(\frac{2}{\sqrt{3}}ight) = \frac{\pi}{6}$.આમ,$x + y = \frac{\pi}{6} + \frac{\pi}{6} = \frac{2\pi}{6} = \frac{\pi}{3}$.

$\tan ^{-1}\left(\frac{1+\sqrt{3}}{3+\sqrt{3}}\right)+\sec ^{-1}\left(\sqrt{\frac{8+4 \sqrt{3}}{6+3 \sqrt{3}}}\right)$ ની કિંમત $.........$ છે.
