已知函数f(x)=2sinwxcoswx-2根下3sin方wx+根下3(w>0)的最小正周期为派

已知函数f(x)=2sinwxcoswx-2根下3sin方wx+根下3(w>0)的最小正周期为派,求w的值,求函数f(x)的单调增区间

已知函数f(x)=2sinwxcoswx-2根下3sin方wx+根下3(w>0)的最小正周期为派,求w的值,求函数f(x)的单调增区间
解析:∵函数f(x)=2sinwxcoswx-2√3sin方wx+√3=sin2wx+√3cos2wx
=2sin(2wx+π/3)
最小正周期为π
∴w=1,f(x)=2sin(2x+π/3)
2kπ-π/2<=2x+π/3<=2kπ+π/2==>kπ-5π/12<=x<=kπ+π/12,f(x)单调增;
2kπ+π/2<=2x+π/3<=2kπ+3π/2==>kπ+π/12<=x<=kπ+7π/12,f(x)单调减;
