    Rewrite cos^6(x) in Terms of the First Power of the Cosine

    Isn't that what i have? cos^6(x)=cos^2(x)*cos^2(x)*cos^2(x) =.5(1+cos2x)*.5(1+cos2x)*.5(1+cos2x) i am lost again :bugeye:

    Rewrite cos^6(x) in Terms of the First Power of the Cosine

    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 :cry: edit ...
