$\tan \left(\frac{1}{4} \sin ^{-1} \frac{\sqrt{63}}{8}\right)$ ની શક્ય કિંમત કઈ છે?

જો ${\sin ^{ - 1}}x + {\cot ^{ - 1}}\left( {\frac{1}{2}} \right) = \frac{\pi }{2}$ હોય,તો $x$ ની કિંમત શોધો.

$x$ ના મૂલ્યોનો ગણ શોધો જેથી $\tan ^{-1}\left(\frac{x}{x-2}\right)-\tan ^{-1}\left(\frac{x}{2 x-1}\right)=\tan ^{-1}\left(\frac{2}{3}\right)$ થાય.

જો $y = \cot^{-1} \left( \frac{1 + x}{1 - x} \right)$ હોય,તો $\frac{dy}{dx} = $
