函数y=sin(x+π/6)-cos(x+π/3)的值域为函数y=sin(x+π/6)-cos(x+π/3)的值域为函数y=sin(x+π/6)-cos(x+π/3)的值域为y=sin(x+π/6)-
函数y=sin(x+π/6)-cos(x+π/3)的值域为
函数y=sin(x+π/6)-cos(x+π/3)的值域为
函数y=sin(x+π/6)-cos(x+π/3)的值域为
y=sin(x+π/6)-cos(x+π/3)
=sinxcosπ/6+cosxsinπ/6 -cosxcosπ/3+sinxsinπ/3
=√3/2sinx+1/2cosx-1/2cosx+√3/2sinx
=√3sinx
所以
值域为【-√3,√3】
