How to rewrite cos x in terms of y

Web5 dec. 2004 · Rewrite the expression in terms of the first power of the cosine: cos^6 x My guess would be that it would be cos (x)*cos (x)*cos (x)*cos (x)*cos (x)*cos (x) I'm not sure if that is it, or any way to start the problem even Please help me edit : cos^6 (x)=cos^2 (x)*cos^2 (x)*cos^2 (x) =.5 (1+cos2x)*.5 (1+cos2x)*.5 (1+cos2x) then ? ? WebThe most straightforward way to obtain the expression for cos(2x) is by using the "cosine of the sum" formula: cos(x + y) = cosx*cosy - sinx*siny. To get cos(2x), write 2x = x + x.
