`int_(0)^( pi)(x sin x)/(1+cos^(2)x)dx`

int_(0)^(pi/2) (sinx)/(1+cos^(2)x)dx

If I_(1) = int_(0)^(pi) (x sin x)/(1+cos^2x) dx , I_(2) = int_(0)^(pi) x sin^(4)xdx then, I_(1) : I_(2) is equal to

int_(0)^(pi) x sin x cos^(2)x\ dx

Evaluate int _(0)^(pi)(x)/(1+ cos^(2)x)dx .

Evaluate: int_0^(pi//2)(sin x)/(1+cos^2x)dx

int_(0)^( pi)(dx)/(1+sin x)

The value of int_(0)^(pi//2) (x+sin x)/(1+cos x)dx , is

int_(0)^(pi) [2sin x]dx=

If A= int _(0)^(pi) (sin x)/(x ^(2))dx, then int _(0)^(pi//2) (cos 2 x )/(x) dx is equal to:

Evaluate : int_(0)^(pi//2) (cos x)/(1+sin^(2) x)dx
