જો $\log_{\pi}x > 0$ હોય,તો $\log_{\pi}\left( \sin^{-1}\frac{2x}{1+x^2} + 2\tan^{-1}x \right)$ ની કિંમત કેટલી થાય?

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.

ધારો કે $f(x) = \cos^{-1}\left(\frac{2x}{1+x^2}\right) + \sin^{-1}\left(\frac{1-x^2}{1+x^2}\right)$,તો $f(1) + f(2)$ ની કિંમત શોધો.
