Algebraic and Geometrical Ability If d/{dx} [\frac{(x^2+1)\sin x}{(\log x) (\sec x)}]= f(x) [\frac{2x}{x^2 + 1}+\cot x-1/{x \log x }-\tan x ], \then f (x) =

Correct Answer is : [(x2+1)sinx(logx)(secx)]

[\frac{(x^2+1)\sin x}{(\log x)(\sec x)}]

(\log x)(\sec x) - (x^2+ 1)\sin x

{(x^2+1)\sin x -2x \cos x}/ {\log x \sec x - \sec x \tan x}
