化简:sinx×cosx×cos2x化简:sinx×cosx×cos2x化简:sinx×cosx×cos2x上图解答给你sinx×cosx×cos2x=1/2sin2x×cos2x=1/4sin4x
化简:sinx×cosx×cos2x
化简:sinx×cosx×cos2x
化简:sinx×cosx×cos2x
上图解答给你
sinx×cosx×cos2x
=1/2 sin2x×cos2x
=1/4 sin4x
化简(cos2x/sinx+cosx)-(cos2x/sinx-cosx)
化简:sinx×cosx×cos2x
y=cos2x+sinx(sinx+cosx) 化简
化简:(sinx+sin2x)/(1+cosx+cos2x)
化简:3.sinx·cosx·cos2x
f(x)=cos2x/cosx+sinx化简
sinx×cos2x-sin2x×cosx
为什么cos2x=cosx*cosx-sinx*sinx
∫cos2x/(sinx+cosx)dx
cos2x/sinx+cosx + 2sinx=
