" 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 ?

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

(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 ) /( 5 sin x-12 cos x+19) is

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

The value of x satisfying the equation (sin^(-1)x)^(3)-(cos^(-1)x)^(3)+(sin^(-1)x)(cos^(-1)x)(sin^(-1)x-cos^(-1)x)=(pi^(3))/(16) is :
