" (34) "log{log(cos x)}

derivative of log {log (cos x}

If int (f(x))/(log cos x) dx = - log(log cos x) + C , then f(x) is equal to a)tan x b) -sin x c) -cos x d) -tan x

If x in(0,(pi)/(2))-{1,(pi)/(4)} then the expression (log_(cos x)(x)*log_(tan x)(x))/(log_(cos x)(x)+log_(tan x)(x)) simplifies to

int (tan x)/(log (cos x))dx

int sin x log(cos x)dx

Differentiate the function (log x)^(cos x)

Differentiate the functions (log x)^(cos x)
