Match for each functions in List - I to its derivative given in List-II
\(\begin{array}{ll}
\hline \text { List I } & \text { List II } \\
\hline \text {(A) } \sin ^{-1}\left(\frac{2 x}{1+x^2}\right) & \text { (I) } \cos x-\sin x \\
\hline \text {(B) } \tan ^{-1}\left(\frac{1-x}{1+x}\right) & \text { (II) } \frac{-1}{1+x^2} \\
\hline \text {(C) } e^{\log (\sin x+\cos x)} & \text { (III) } \frac{2}{1+x^2} \\

Step-by-step Solution
Detailed explanation
(A) Let \(y=\sin ^{-1}\left(\frac{2 x}{1+x^2}\right)\) Again, let \(x=\tan \theta=\sin ^{-1}\left(\frac{2 \tan \theta}{1+\tan ^2 \theta}\right)\)…
