(1)f(x)=(1/2)sin2x+1,x0=kπ+π/4.g(x0)=[cos(kπ+π/4+π/12)]^2=[cos(kπ+π/3)]^2=(+-cosπ/3)^2=1/4.(2)h(x)=(1/2)sinwx+1+[cos(wx/2+π/12)]^2=(1/2)sinwx+(1/2)cos(wx+π/6)+3/2=(1/2)sinwx+(1/2)coswxcosπ/...(1)f(x)=(1/2)sin2x+1，x0=kπ+π/4。x0不是等于kπ/2+π/4吗？哎呀。我总写错哈那后面应该都错了吧？(1)g(x0)=[cos(kπ/2+π/4+π/12)]^2=[cos(kπ/2+π/3)]^2=(+-sinπ/3)^2=3/4。(2)与(1)无关
