设(sinx)=2-cos2x,则f(cosπ/6)=?设(sinx)=2-cos2x,则f(cosπ/6)=?设(sinx)=2-cos2x,则f(cosπ/6)=?原式=f[sin(0/2-π/6
设(sinx)=2-cos2x,则f(cosπ/6)=?
设(sinx)=2-cos2x,则f(cosπ/6)=?
设(sinx)=2-cos2x,则f(cosπ/6)=?
原式=f[sin(0/2-π/6)]
=f(sin(π/3))
=2-cos(2*π/3)
=2-(-1/2)
=5/2
设f(sinx)=3-cos2x,则f(cosx)=?
设f(sinx)=cos2x,则f(1/3)等于?
设f(sinx)=2-cos2x求f(cosx)
设f '(sinx^2)=cos2x+tanx^2 (0
设f(sinx)=cos2x,则f(根号3/2)等于
设f(sinx)=cos2x,则f(根号3/2)等于
设(sinx)=2-cos2x,则f(cosπ/6)=?
若f(sinx)=2-cos2x,则f(cosx)等于?
设f(sinX)=cos2X,求f(cosX)的表达式
设f(sinx)=cos2x,求f(cosx)
设f(sinx)=cos2x+1,求f(cosx)
设f(sinx)=cos2x+1求f(cos*x)
设f(sinx)=cos2x+1.求f(cosx)
设f(sinx)=1+cos2x 则f(x)=
如果f(sinx)=3-2cos2x,则f(cos2x)等于多少?
若f(sinx)=cos2x,则f(cos)的值为 A sinx B cos2x C -cos2x D -sin2x跟二倍角无关哦,
f ‘(sinx )=2— cos2x 则 fx =
