" 8) "int_(0)^( pi)(x tan x)/(sec x+tan x)=(pi)/(2)(pi-2)

int_(0)^(pi)(x tanx)/(sec x +tan x)dx

int_(0)^(pi) (x tan x)/( sec x + tan x) dx=

int_(0)^(pi) (tan x)/(sec x + cos x) dx=

Evaluate int_(0)^( pi)(x tan x)/(sec x+tan x)dx

Using properties of definite integrals,prove the following : int_(o)^( pi)(x tan x)/(sec x csc x)dx=(pi^(2))/(4)

int_(0)^( pi)(x tan x)/(tan x+sec x)*dx=(pi(pi-2))/(2)

int_(0)^( pi)x(tan x)/(sec x+cos x)dx=(pi^(2))/(4)

Evaluate :int_(0)^( pi)(x tan x)/(sec x+tan x)dx

Evaluate: int_(0)^( pi)(x tan x)/(sec x+tan x)dx
