" 16."((4-7sin x)/(cos^(2)x))

int((4-7sin x)/(cos^(2)x))

2cosx-cos3x-cos5x= ............... A) 16 cos ^(3) x sin ^(2) x B) 16 sin^(2) x cos ^(2) x C) 4 cos ^(2) x sin ^(2) x D) 4 sin ^(2) x cos ^(2)x

int_(0)^(pi//2) (16sin x. cos x)/(sin^(4) x + cos^(4)x)dx=

Solve the equation 5sin^(2)x-7sinx cosx+16cos^(2)x=4

If 2^(sin x+cos y)=1 and 16^(sin^(2)x+cos^(2)y)=4 , then find the value of sin x and cos y

Prove that int_(0)^((pi)/(2))(x sin x cos xdx)/(cos^(4)x+sin^(4)x)=(pi^(2))/(16)

If x in(0,(pi)/(2)), thenshowthat(d)/(dx)cos^(-1){(7)/(2)(1+cos2x)+(sqrt(sin^(2)x-48cos^(2)x))sin x}=1+(7sin x)/(sqrt(sin^(2)-48cos^(2)x))

The values of x satisfying the system of equation 2^("sin" x + "cos"y) = 1, 16^("sin"^(2)x + "cos"^(2)y) =4 are given by

The values of x satisfying the system of equations 2^(sin x-cos y)=1,16^(sin^(2)x+cos^(2)y)=4 are given by :
