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

Evaluate: (i) int(sec x)/(log(sec x+tan x)dx) (ii) int(cos ecx)/((log tan x)/(2))dx

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

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

Evaluate: int("cosec x")/(log tan(x/2)) dx

int (cos ecx) / (log (tan ((x) / (2)))) dx

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

int sin x log(cos x)dx
