请问f(x)=根号3sin(wx+φ)-cos(wx+φ)=2Sin(wx+φ-π/6)如何化简?
请问f(x)=根号3sin(wx+φ)-cos(wx+φ)=2Sin(wx+φ-π/6)如何化简?
请问f(x)=根号3sin(wx+φ)-cos(wx+φ)=2Sin(wx+φ-π/6)如何化简?
f(x)=根号3sin(wx+φ)-cos(wx+φ)=2[根号3sin(wx+φ)/2-cos(wx+φ)/2]=2[sin(wx+φ)cos(π/6)-cos(wx+φ)sin(π/6)]=2Sin(wx+φ-π/6)
请问f(x)=根号3sin(wx+φ)-cos(wx+φ)=2Sin(wx+φ-π/6)如何化简?
[非常急]已知函数f(x)=根号3sin(wx+φ)-cos(wx+φ)(0
已知函数f(x)=根号3sin(wx+φ)-cos(wx+φ)(0
已知函数f(x)=根号3sin(wx+φ)-cos(wx+φ)(0
已知函数f x 根号3sin(wx+φ)-cos(wx+φ)(w>0,0
求教：已知f(x)=根号3*sin(wx+a)-cos(wx+a) (0
f(x)=根号3sin(wx+q)-cos(wx+q),（w>0,0
已知函数f(x)=根号3sin(wx+a)-cos(wx+a)(0
已知函数f(x)=根号3sin(wx+fai)-cos(wx+fai)(0
已知函数f(x)=根号3sin（wx+φ）（0
已知函数f(x)=根号3sin(wx+φ)++(w>0,-π/2
已知函数f(x)=根号3sin(wx+φ)++(w>0,-π/2
化简f（x）=2又根号3sin（wx／2）cos（wx／2）-2sin^2wx／2
f(x)=sin^2 wx+根号3*sinwxcoswx麻烦化简成y=ASin(wx+@)+B的形式.
