" 22."5cos x-3sin x+(2)/(cos^(2)x)

int(5cos x-3sin x+(2)/(cos^(2)x))dx

Solve sin 3x + sin x + 2 cos x = sin 2x + 2 cos^(2)x

int(3sin x-2)cos x(dx)/(5-cos^(2)x-4sin x)

If cos x sin x = 0.22, then (cos x - sin x)^(2)=

int (sin ^ (2) x cos ^ (2) x) / ((sin ^ (5) x + cos ^ (3) x sin ^ (2) x + sin ^ (3) x cos ^ (2) x + cos ^ (5) x) ^ (2)) dx

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

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(5cos^3x+7sin^3x)/(3sin^2xcos^2x)dx

int(5cos^3x+7sin^3x)/(3sin^2xcos^2x)dx

Prove that : (cos 9x - cos 5x)/(sin 17x -sin 3x)=- (sin 2x)/(cos 10x) .
