Question
फलन $\frac{{{{10}^x} - {{10}^{ - x}}}}{{{{10}^x} + {{10}^{ - x}}}}$ का प्रतिलोम है
$\Rightarrow x = \frac{1}{2}{\log _{10}}\left( {\frac{{1 + y}}{{1 - y}}} \right)$
माना $y = f(x)$ ==> $x = \pi ,\,\,f(\pi ) = - \tan \frac{\pi }{4} = - 1$
==> ${f^{ - 1}}(y) = \frac{1}{2}{\log _{10}}\left( {\frac{{1 + y}}{{1 - y}}} \right)$
==> $g({\sin ^2}x) = \,|\sin x|$.
