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

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

If A=int_((rho)/(2))^((pi)/(2))cos(sin x)dxB=int_(0)^((pi)/(2))sin(cos x)dx and C=int_(0)^((pi)/(2))cos(x)dx

int_(0)^( pi)|cos x|dx=2

Evaluate: int_(0)^( pi/2)sqrt(1-cos2x)dx

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

If I_(1)=int_(0)^(pi//2)"x.sin x dx" and I_(2)=int_(0)^(pi//2)"x.cos x dx" , then

If A = int_(0)^((pi)/(2))(sin^(3)x)/(1+cos^(2)s)dx and B=int_(0)^((pi)/(2))(cos^(2)x)/(1+sin^(2)x)dx , then (2A)/(B) is equal to

int_(0)^(2 pi)|cos x|dx
