函数y=sin(wx).cos(wx)最小正周期是4帕 ,那么常数W是

已知函数y=cos²wx-sin²wx的最小周期是π/2,那么正数= 函数y=sin(wx).cos(wx)最小正周期是4帕 ,那么常数W是 函数y=cos^2wx-sin^2wx的最小正周期是π,则函数f(x)=2sin(wx+π/4)的一个单调递增函数y=cos^2wx-sin^2wx(w大于0）的最小正周期是兀,则函数y=2sin(wx+兀/4）的单调增区间是多少? 设函数f(x)=sin(wx+φ)+cos(wx+φ)(w>0,|φ| 设函数f(x)=sin(wx+φ)+cos(wx+φ)(w>0,|φ| 设函数f(x)=sin(wx+φ)+cos(wx+φ)(w>0,|φ| 设函数f(x)=sin(wx+φ)+cos(wx+φ)(w>0,|φ| [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)=√3sin(wx+φ)-cos(wx+φ)(0 老师好：设函数f(x)=sin(wx+φ)+cos(wx+φ)(w>0,|φ| 设函数f(x)=sin(wx+φ)+cos(wx+φ)(w>0,|φ| 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+φ)-cos(wx+φ)(0 设函数f(x)=sin(wx+g)+cos(wx+g) (w>0,|g| 设函数f(x)=sin(wx+q)+cos(wx+q)(w>0,q的绝对值 已知函数f(x)=√3 sin( wx+φ)-cos(wx+φ) (0 已知函数f(x)=根号3sin(wx+fai)-cos(wx+fai)(0
