sin2x = 2sinxcosx cos2x= 2(cosx)^2 1
 one year ago

RolyPolyBest ResponseYou've already chosen the best response.1
\[=2\sin x\sin(2x)+ \cos(2x)(\cos x)\]\[=2\sin x(2\sin x \cos x)+ (2cos^2x1)(\cos x)\]
 one year ago

RolyPolyBest ResponseYou've already chosen the best response.1
For the first term, you'll get 4(sinx)^2 cosx (sinx)^2 = 1(cosx)^2
 one year ago

RolyPolyBest ResponseYou've already chosen the best response.1
Then you can express it in terms of cosx, if that's what you want.
