વિધેયને તેના સરળ સ્વરૂપમાં લખો: $\tan ^{-1}\left(\frac{3 a^{2} x-x^{3}}{a^{3}-3 a x^{2}}\right), a>0 ; \frac{-a}{\sqrt{3}} \leq x \leq \frac{a}{\sqrt{3}}$

વિધાન $I:$ સમીકરણ $(\sin^{-1} x)^3 + (\cos^{-1} x)^3 - a\pi^3 = 0$ નો ઉકેલ તમામ $a \ge \frac{1}{32}$ માટે મળે છે.
વિધાન $II:$ કોઈપણ $x \in [-1, 1]$ માટે,$\sin^{-1} x + \cos^{-1} x = \frac{\pi}{2}$ અને $0 \le (\sin^{-1} x - \frac{\pi}{4})^2 \le \frac{9\pi^2}{16}$ છે.

જો $y = \tan^{-1} \sqrt{\frac{1 + \cos x}{1 - \cos x}}$ હોય,તો $\frac{dy}{dx}$ શું થાય?

જો $\sin ^{-1}\left(\frac{x}{5}\right)+\operatorname{cosec}^{-1}\left(\frac{5}{4}\right)=\frac{\pi}{2}$ હોય, તો $5+x=$

$\sin \left\{ {{\sin }^{ - 1}}\frac{1}{2} + {{\cos }^{ - 1}}\frac{1}{2} \right\} = $
