0quad (sin x)/(cos2 pi)

int _(0)^(pi//2) (cos x - sin x)/(1+cos x sin x)dx is equal to

The number of solutions that the equation sin (cos (sin x))= cos (sin (cos x)) has in [0, (pi)/(2)], is "_____"

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

Prove that: int_(0)^( pi/2)(sin x)/(sin x-cos x)dx=(pi)/(4)

Write the value of: overset(pi/2)underset(0)int (sin x)/(sinx +cos x)(dx)-overset(pi/2)underset(0)int(cos x)(sin x+cos x)(dx)

The number of solution for , {:(sin(x-(pi)/4)-cos(x+(3pi)/4)=1),(" "(2cos 7x)/(cos 3+sin3) gt 2^(cos 2x)):}}" in" (0,2pi) is

(d)/(dx)cos x^(0) = (A) -sin x^(0) (B) -(pi)/(180)sin x^(0) ( C) (pi)/(180)sin x^(0) (D) (2 pi)/(180)sin x^(0)
