f(x)=sin^2(wx)+√3sin(wx)*sin(wx+π/2)w>0的最小正周期为π,求w,f(x)在闭区间0,2π/3上取值范围f(x)=sin^2(wx)+√3sin(wx)*sin(w
f(x)=sin^2(wx)+√3sin(wx)*sin(wx+π/2)w>0的最小正周期为π,求w,f(x)在闭区间0,2π/3上取值范围
f(x)=sin^2(wx)+√3sin(wx)*sin(wx+π/2)w>0的最小正周期为π,求w,f(x)在闭区间0,2π/3上取值范围
f(x)=sin^2(wx)+√3sin(wx)*sin(wx+π/2)w>0的最小正周期为π,求w,f(x)在闭区间0,2π/3上取值范围
f(x)=sin^2(wx)+√3sin(wx)*sin(wx+π/2)
=(1-cos2wx)/2+√3sinwx*coswx
=1/2-cos2wx/2+√3sin2wx/2
=1/2+sin(2wx-π/6)
最小正周期=2π/2w=π
w=1
f(x)=1/2+sin(2x-π/6)

f(x)=sin(2wx)+√3cos(2wx)怎么化成f(x)=sin(2wx+π/3)
已知函数f x=√3sin(wx+φ/2)*cos(wx+φ/2)+sin^2(wx+φ/2)(w>0,0
已知函数f(x)=√3sin(wx+φ)-cos(wx+φ)(0
已知函数f(x)=√3 sin( wx+φ)-cos(wx+φ) (0
已知函数f(x)=√3 sin( wx+φ)-cos(wx+φ) (0
已知函数f(x)=√3sin(wx+φ)-cos(wx+φ)(0
f(x)=sin^2(wx)+√3sin(wx)*sin(wx+π/2)w>0的最小正周期为π,求w,f(x)在闭区间0,2π/3上取值范围
f(x)=sin^2(wx)+√3sin(wx)*sin(wx+π/2)w>0的最小正周期为π,求w,f(x)在闭区间0,2π/3上取值范围
化简f(x)=2又根号3sin(wx/2)cos(wx/2)-2sin^2wx/2
请问f(x)=根号3sin(wx+φ)-cos(wx+φ)=2Sin(wx+φ-π/6)如何化简?
设函数f(x)=sin(wx+t)(-π/2
设函数f(x)=sin(wx+t)(-π/2
函数f(x)=√3sin^(wx/2)+sin(wx/2)cos(wx/2) (w>0)的周期为π,求w的值和函数f(x)的单调递增区间
已知函数为f(x)=√3sin(wx+φ)-cos(wx+φ)(w>0,0
f(x)=sin^2 wx+根号3*sinwxcoswx麻烦化简成y=ASin(wx+@)+B的形式.
[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
求教:已知f(x)=根号3*sin(wx+a)-cos(wx+a) (0
