. (cos(2x)) Sin(x) = Prove The Identity. 8(tan(x) - Cot(x)) = 4 Sin(2x) Tan?(x) - Cot2(x) Factor The Denominator And Then Simplify. 8(tan(x) – Cot(x)) 8(tan(x) - Cot(x)) Tan2(x) - Cot2(x) (tan(x) Prove that cos4x=1-8sin^2xcos^2xyou can solve cos4x as cos2(2x) =1-2sin 2 (2x) =1-2(2sinx .

### f (x)=sin^4x + cos^4x. Derivate of above gives you this below result. f' (x)=4sin^3x cosx - 4cos^3xsinx. Taking out the common part i.e 4sinxcosx. f' (x)=4sinxcosx (sin^2x - cos^2x) f' (x)=-2.2sinxcosx (cos^2x -sin^2x) 2sinxcosx = sin2x and cos^x-sin^x = cos2x. f' (x)=-2sin2x.cos2x. So its -4sin4x.
