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

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

Evaluate: int cos x 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

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

(cosec x)/(log ("tan"(x)/(2)))

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)

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

By using L' Hospital's rule, evaluate : Lim_(x rarr (pi)/(2)) (cos x log tan x).

Find ( dy)/( dx) at x = pi//4 for x = a [ cos t + log( tan ((t)/(2)))] and y = a sin t
