int_(0)^(pi)(cos x)/(1-sin^(m)x)dx

int_(0)^(pi/2)(1)/(6-cos x)dx

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

int_(0)^( pi/4)(1+sin2x)/(cos x+sin x)dx

int_(0)^(pi//6) sqrt(1-sin 2x) dx

int_(0)^(pi//6) sqrt(1-sin 2x) dx

int_(0)^(pi//2) (Cos x)/(1+Sin x) dx=

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

If int_(0)^(pi/2) f ( sin2 x ) sin x dx = A int_(0)^(pi/4) f ( cos 2 x ) cos x dx then the value of A is ( sqrt2 = 1.41)
