" 76."int cos x log(tan x/2)dx=

Evaluate: int cos x log(tan(x)/(2))dx

If int cos x log (tan""(x)/(2))dx = sin x log (tan""(x)/(2)) + f(x) then f(x) is equal to, (assuming c is a arbitrary real constant)

int sec x ln(sec x+tan x)dx=

int sec x ln(sec x+tan x)dx=

int (cosec x)/(log (tan)x/2)dx =

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

Integrate : int sin x log (sec x+tan x)dx

int cosx.log (tan""(x)/(2)) dx =

int sin x log(cos x)dx

int sec x log (sec x+ tan x)dx=
