$\sin ^{-1}\left(\frac{12}{13}\right)+\cos ^{-1}\left(\frac{4}{5}\right)+\tan ^{-1}\left(\frac{63}{16}\right)=$

$x, y, z$ એ $G$.$P$. માં છે અને $\tan^{-1} x, \tan^{-1} y, \tan^{-1} z$ એ $A$.$P$. માં છે,તો

ધારો કે $S = \{ x : \cos^{-1} x = \pi + \sin^{-1} x + \sin^{-1}(2x + 1) \}$. તો $\sum_{x \in S} (2x - 1)^2$ ની કિંમત . . . . . . છે.

જો $k = \tan(\frac{\pi}{4} + \frac{1}{2}\cos^{-1}(\frac{2}{3})) + \tan(\frac{1}{2}\sin^{-1}(\frac{2}{3}))$ હોય, તો સમીકરણ $\sin^{-1}(kx-1) = \sin^{-1}x - \cos^{-1}x$ ના ઉકેલોની સંખ્યા . . . . . . છે.
