函数f(x)=3sin(2x-π/8),对任意的x属于R都有f(x1)≤f(x)≤f(x2),则x1-x2的绝对值的最小值是?

已知函数f(x)=2根号3sin平方x-sin（2x-π/3) 已知函数f(x)=sin(π-x)sin(π/2-x)+cos²x(1)求函数f(x)的最小正周期(2)当x[-π/8,3π/8]时,求函数f(x)的单调区间 判断下列函数的奇偶性 f(x)=[sin(π/2+x)cos(π/2-x)tan(-x+3π)]/[sin(7π-x)tan(8π-x)] 设函数f (x)=cos(2x-π/3)-2sin平方x (1)求函数f(x 设函数f(x)=sin(3x)+|sin(3x)|,函数的最小正周期为什么是2π? 设函数 f(x)=sin(2x+y),(-π 设函数f(x)=sin(2x+φ)(-π 设函数f(x)=sin(2x+φ)(-π 设函数f x=SIN(2X+φ)(-π 设函数f(x)=sin(2x+φ)(-π 设函数f(x)=sin(2x+φ)(-π 已知函数F(X)=SIN(2X+φ)(-π 设函数f(x)=sin(2x+φ)(-π 设函数f(x)=sin(2x+φ)(-π 设函数f(x)=sin(2x+ φ)(-π 设函数f(x)=sin(2x+φ)(-π 函数f(x)=sin(2x+a) -π 设函数f(x)=sin(2x+ φ)(-π
