int_(0)^( pi/3)(cos x)/(3+4sin x)dx

int_(0)^( pi/6)(cos x)/(3+4sin x)dx

Evaluate (i) int_(0)^(pi/3) (cos x)/(3+ 4 sin x)dx

int_(0)^(pi//2)(cos x)/((3+sin x)(4+sin x))dx=

int_(0)^(2 pi)(cos x)/(sqrt(4+3sin x))dx

solve int_(0)^( pi/3)(4sin x)/(cos^(2)x)dx

Suppose _((pi)/(2))cos(pi sin^(2)x)dx and I_(2)int_(0)^(3)cos(2 pi sin^(2)x)dx and I_(3)=int_(0)^((pi)/(2))cos(pi sin x)dx, then

u,=int_(0)^((pi)/(2))cos((2 pi)/(3)sin^(2)x)dx and v,=int_(0)^((pi)/(2))cos((pi)/(3)sin x)dx

int_(0)^(pi)(cos^(4)x-sin^(4)x)dx=
