int_(0)^(2 pi)(dx)/(2+sin2x)

" 0."int_(0)^( pi/4)(dx)/(2+sin^(2)x)=

Evaluate :int_(0)^( pi)(x^(2)sin2x*sin((pi)/(2)*cos x))/(2x-pi)dx

int_(0)^( pi/4)(x^(2)(sin2x-cos2x))/((1+sin2x)cos^(2)x)dx

int_(0)^((pi)/(2))log(sin2x)dx

Show that int_(0)^((pi)/(2))log(sin2x)dx=-(pi)/(2)(log2)

Evaluate: int_(0)^( pi)(x sin2x sin((pi)/(2)cos x))/(2x-pi)dx

int_(0)^( pi)(x sin2x sin((pi)/(2)cos x))/(2x-pi)dx is equal to

int_(0)^(1)(tan^(-1)x)/(x)dx is equals to int_(0)^((pi)/(2))(sin x)/(x)dx(b)int_(0)^((pi)/(2))(x)/(sin x)dx(1)/(2)int_(0)^((pi)/(2))(sin x)/(x)dx(d)(1)/(2)int_(0)^((pi)/(2))(x)/(sin x)dx
