已知函数f(x)=sin(wx)cos(wx)(w>0,x属于R)的最小正周期为派,则w=

解答
f(x)=1/2*sin2wx
w>0
所以T=2π/2w=π
w=1
推荐
设函数f(x)=sin(wx+φ)+cos(wx+φ)(w>0,|φ
已知函数f(x)=sin(π-wx)cos wx+cos的平方wx(w大于0)的最小正周期为π
高中数学已知函数f(x)+sin(π-wx)coswx+cos²wx(w>0)的最小正周期为π
已知函数f(x)=sin(π/3+wx)+cos(wx-π/6)(w>0)f(x)的最小正周期为π
已知函数f(x)=sin(π-wx)cos wx+cos的平方wx(w大于0)的最小正周期为π 求w的值
