f(x)＝2√3sin(3wx+兀/3)(w>0).若f(x+Q)是周期为

f(x)=sinwxcosPai/3+coswxsinPai/3-coswxcosPai/6+sinwxsinPai/6+coswx=sinwx+coswx=根号2sin(wx+Pai/4)T=2Pa

f(x)=(1-cos2wx)/2+√3/2*sin2x=(√3/2)sin2wx-1/2*cos2wx+1/2=√[(√3/2)^2+(1/2)^2]*sin(2wx-z)+1/2其中tanz=(1

cos(π/2-wx）=sin（wx）所以f(x)=sin^2wx+根号3coswxsin（wx）所以=二分之（根号三加二）乘sin^2wx因为相邻两条对称轴之间的距离为π\2所以w=1）求W的值及f

1.f(x)=根号3sin(wx+a)-cos(wx+a)当a+π/3=kπ时f(x)为偶函数,而0<a<π,则a+π/3=πf(x)=2coswx,而函数y=f(x)图象的两相邻对称轴间

(1)f(x)=sin²ωx+2√3sin(ωx+π/4)cos(ωx-π/4)-cos²ωx-√3=2√3·√2/2(sinωx+cosωx)·√2/2(sinωx+cosωx)

(1)f(x)=根号3sin(wx+φ)-cos(wx+φ)=2Sin(wx+φ-π/6)由于是偶函数,即f(x)=f(-x）即2Sin(wx+φ-π/6)=2Sin(-wx+φ-π/6)即Sinwx

把三角函数分解,利用公式sin(x+y)=sinxcosy+cosxsiny,然后把2sin[wx-(π/6)]sin[wx+(π/3)分解开乘起来,与sin[2wx-(π/3)]相等,求解

(1)f(x)=2sin(wx-π/6)•sin(wx+π/2-π/6)=2sin[π/2+(wx-π/6)]•sin(wx-π/6)=2cos(wx-π/6)•s

f(x)=√[(√3)²+1²]*sin(wx+q-z)=2sin(wx+q-z)tanz=1/√3所以z=π/6f(x)=2sin(wx+q-π/6)sin的对称轴是取最值的地方

f(x)=√3sin²(wx/2)+sin(wx/2)cos(wx/2)=-(√3/2)*[1-2sin²(wx/2)-1]+(1/2)*2sin(wx/2)cos(wx/2)=-

（1)f(x)=根号3sin(wx+φ)-cos(wx+φ)=2Sin(wx+φ-π/6)由于是偶函数,即f(x)=f(-x）即2Sin(wx+φ-π/6)=2Sin(-wx+φ-π/6)即Sinwx

f(x)=(√3)sin(ωx+φ)-cos(ωx+φ)=2{[(√3)/2]sin(ωx+φ)-(1/2)cos(ωx+φ)}=2[sin(π/3)sin(ωx+φ)-cos(π/3)cos(ωx+

已知函数f(X)=sin^2wx+根号3sinwx*sin(wx+π/2)+2cos^2wx,x属于R,在y轴右侧的第一个最高点的横坐标为π/6,求w；若将函数f(x)的图像向右平移π/6个单位后,再

先化简得f(x)=2sin(wx+a-π/6)由偶函数得出a的值为2π/3,由图像的两相邻对称轴间的距离为π/2得T=π,则w=2,所以f(x)=2sin(2x+π/2)

f(x)=√3sin(wx+φ/2)*cos(wx+φ/2)+sin^2(wx+φ/2)=(√3/2)sin(2wx+φ)+(1/2)[1-cos(2wx+φ)]=sin(2wx+φ-π/6)+1/2

已知函数f(x)=(√3)sin(ωx+φ)-cos(wx+φ)(0

f(x)=sin^2wx+√3sinwxsin(wx+π/2)=sin^2wx+√3sinwxcoswx=1/2(1-cos2wx)+√3/2sin2wx=√3/2sin2wx-1/2cos2wx+1

已知函数f(x)=√3sin(wx+φ)+cos(wx+φ)(|φ|0)的最小正周期为π,且f(-x)=f(x),则下列关于g(x)=sin(wx+φ)的图像说法正确的是（）A.关于点（π/6,0）对

(1)f(x)=√3sin(wx+φ)-cos(wx+φ)=2sin(wx+φ-π/6)相邻对称轴间的距离为π/2,最小正周期为π所以w=2π/π=2又知f(0)=2sin(φ-π/6)=00
