已知函数f(x)=cos(2x-π/3)+2sin(x-π/4)sin(x+π/4)求函数f(x)在区间[0,π/2]上的值域
已知函数f(x)=cos(2x-π/3)+2sin(x-π/4)sin(x+π/4)求函数f(x)在区间[0,π/2]上的值域
已知函数f(x)=cos(2x-π/3)+2sin(x-π/4)sin(x+π/4)求函数f(x)在区间[0,π/2]上的值域
f(x)=cos(2x-π/3)+2sin(x-π/4)sin(x+π/4) f(x)=1/2cos 2x+√3/2sin 2x+2(sin x-cos x)(xin x+cos x) =1/2cos 2x+√3/2sin
我勒个去的，楼主，我为了做任务来到你这里，不要介意，你的问题我实在答不出来。。。
