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

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

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

Prove that: ,,(sin x-sin3x)/(sin^(2)x-cos^(2)x)=2sin x

Prove that (sin x-sin 3 x)/(sin ^(2) x-cos ^(2) x)=2 sin x

Prove the following: (sin x -sin 3x)/(sin^2 x -cos^2 x)= 2sinx

If f(x) = |(1+sin^(2)x,cos^(2)x,4 sin 2x),(sin^(2)x,1+cos^(2)x,4 sin 2x),(sin^(2)x,cos^(2)x,1+4 sin 2x)| What is the maximum value of f(x)?

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

(sin x + cos x)^2 + (sin x - cos x)^2

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