19.(1)/(sin x cos^(3)x)

If k_(1)=sin x cos^(3)x and k_(2)=cos x sin^(3)x then

What is the value of (sin^(3) x + cos^(3) x)/( sin x + cos x) + sin x cos x ?

Integrate the following: int{(5cos^(3)x+2sin^(3)x)/(2sin^(2)x*cos^(2)x)+sqrt(1+sin2x)+(1+2sin x)/(cos^(2)x)+(1-cos2x)/(1+cos2x)}dx

(sin^(3)x+cos^(3)x)/(sin x+cos x)+(sin^(3)x-cos^(3)x)/(sin x-cos x)=2

3 sqrt(3) sin^(3) x + cos^(3) x + 3 sqrt(3) sin x cos x = 1

The maximum value of (3)/(5sin x-12cos x+19)

3. (sin x+cos x)(1-sin x cos x)=sin^(3)x+cos^(3)x

Solve for x, the equation sin^(3)x+sin x cos x+cos^(3)x=1

Integrate the following: int{(5cos^3x+2sin^3 x)/(2sin^2 x*cos^2 x)+sqrt(1+sin2x)+(1+2sin x)/(cos^2x)+(1-cos2x)/(1+cos 2x)}dx
