f(cosπ/6)
=f(sinπ/3)
=3-cos(2×π/3)
=3-(-1/2)
=7/2

若f(cosX)=3-cos2X,则f(sinX) 若f(sinX)=3-cos2X,则f(cosX)为设f(sinx)=cos2x+1求f(cos*x) 若f(sinx)=3-cos2x,则f(cosx)=3+cos2x 若f(cosx)=cos2x,则f(sinx)=? 若f(sinx)=2-cos2x,则f(cosx)等于? 设f(sinx)=cos2x,则f(1/3)等于? 若f(cosx)=cos2x,且cosx-sinx=4/5,则f(sin2x/cos(x+派/4)=? 若f（sinx）=3-cos2x，则f（cosx）=______．若f（sinX）=3—cos2X,则f(cosX)等于若f（sinx）=3-cos2x,则f（cosx）等于（）函数f(x)=sinx -cos2x取得最大值,则cos x等于
