$\tan \left(2 \tan ^{-1}\left(\frac{3}{5}\right)+\sin ^{-1}\left(\frac{5}{13}\right)\right)$ ની કિંમત શોધો:

ધારો કે $\tan ^{-1}\left(\tan \frac{5 \pi}{4}\right) = \alpha$ અને $\tan ^{-1}\left(-\tan \frac{2 \pi}{3}\right) = \beta$. તો:

$2 \pi - \left(\sin ^{-1} \frac{4}{5} + \sin ^{-1} \frac{5}{13} + \sin ^{-1} \frac{16}{65}\right)$ ની કિંમત શોધો.

$2 \cos ^{-1} x = \sin ^{-1} \left( 2 x \sqrt{1 - x^2} \right)$ એ $x$ ની કઈ કિંમતો માટે સાચું છે?

જો $\sin ^{-1} a=\alpha+\beta$ અને $\sin ^{-1} b=\alpha-\beta$ હોય,તો $\sin ^2 \alpha+\cos ^2 \beta=$ . . . . . . .
