Answer :

let y = xcos x + (sin x)tan x


y = a + b


where a= xcos x ; b = (sin x)tan x




a= xcos x


Taking log both the sides:


log a= log (x)cos x


log a= cos x log x


{log xa = alog x}


Differentiating with respect to x:











b = (sin x)tan x


Taking log both the sides:


log b= log (sin x)tan x


log b= tan x log (sin x)


{log xa = alog x}


Differentiating with respect to x:
