请求天才!f(x)=sinπx/(x^2+1)(x^2-2x+2) 求此函数的最大值和最小值!

请求天才!f(x)=sinπx/(x^2+1)(x^2-2x+2) 求此函数的最大值和最小值! 函数y=2sin(x-π/6)(x∈[0,π])的值域请求详解 f(sin^2x)=x/sinx 求f(x) f(x)=sin(x+π/4)图像怎样变成F(x)=cos(2x) f(x)=（1+cotx)sin^2x-2sin(x+π/4)sin(x-π/4)还有一题, 已知函数f(x)=(1+1 anx)sin^2x+m sin(x+π/4)sin(x-π/4) 为什么 f(x)=sin(x+π/2)=cosx 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
