" (ix) "(cos x-sin x)/(cos x+sin x)(2+2sin2x)

Evaluate: int(cos x-sin x)/(cos x+sin x)(2+2sin2x)dx

Solve the following integration int (cos x - sin x)/(cos x + sin x)*(2+2 sin 2x)dx

Solve the following integration int (cos x - sin x)/(cos x + sin x)*(2+2 sin 2x)dx

Solve the following integration int (cos x - sin x)/(cos x + sin x)*(2+2 sin 2x)dx

Prove that (cos x + sin x)/(cos x - sin x) - (cos x - sin x)/(cos x + sin x) = 2 tan x

2tan2x = (cos x + sin x) / (cos x-sin x) - (cos x-sin x) / (cos x + sin x)

Prove that: (i) (1+"sin" 2theta-cos 2theta)/(1+"sin" 2theta+cos 2theta)="tan" theta . (ii) 2 tan 2x=(cos x+"sin" x)/(cos x-"sin" x)-(cos x-"sin" x)/(cos x+"sin" x) .

if a=(1+sin x)/(1-cos x+sin x) then (1+cos x+sin x)/(2sin x) is

Prove that : (cos 4x sin 3x - cos 2x sin x)/(sin 4x .sin x + cos 6x .cos x) = tan 2x

(cos^(3) x- sin^(2) x)/(cos x - sin x)=(1)/(2) (2 + sin 2x)
