New questions in Mathematics. Explain how you would make use of triangle Nov 05, 2018 · a) By considering De Moivre's Theorem with n=4 and n=2, express cos 4 x in the form: cos 4 x = Acos(4x) + Bcos(2x) + C, where A, B and C are constants which you should determine.
Formula of cos 4x, ie you need the angle in x form… Since, we know cos 2x = cos²x - sin²x & sin2x = 2sinxcosx By applying the above.. So, cos 4x = cos 2*2x = cos² 2x - sin² 2x = ( cos 2x)² - (sin 2x)² = ( cos²x - sin²x )² - (2sinx*cosx)² = cos^4 x

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.
