解答
设函数f(x)=cos(2x 派/3) sin^2 x?1:求f(x)的值域和最小正故值域为[1/2-根号3除以2,1/2 根号3除以2],最小正周其为π
推荐
已知函数f(x)=sin(2x-π/6)-2cos(x-π/4)cos(x+π/4)+1,求f(x)的最小周期及在区间【0,π/2】上的值域
已知函数f(x)=sin(2x+π/6)+sin(2x-π/6)-2cos^2x 1.f(x)的值域和最小正周期 2.y=f(x)的单调增区间
已知函数f=sin-2cos+1,求f的最小正周期求函数f在区间《0,0.5π》上的值域
已知函数f(x)=2cos(x+π/3)[sin(x+π/3)-更号3倍的cos(x+π/3)]求f(x)的值域和最小正周期
求函数f(x)=cos^4x-2cos^2 2x +sin^x的值域和最小正周期
