y=sin(π/3-2x)在(-π/2.π/2)上的减区间

y=sin(π/3-2x)在(-π/2.π/2)上的减区间 判断单调性 y=sin(x-π/6) y=sin(-2x+π/3) 1.y=x*e^(2x) 2.y=(sin(2x))/x 3.y=sin(3x+(π/3))怎么求导数! 1.y=sin(-X+π/6)2.y=cos(-2X+π/3) 函数y=sin(2x+α)cos(x+α)-cos(2x+α)sin(x+α)在x=π/3处的导函数为 y=sin(x+π/3)周期 y=12sin(2x+π/6)+5sin(π/3-2x)最大值 y=12sin(2x+π/6)+5sin(π/3-2x)的最大值 y=sin(x+π/3)sin(x+π/2)化简 函数y=2sin(π/3-X)+sin(π/6+X)的最大值 周期y=sin(x+π/3)sin(x+π/2) 的最小正周期是多少 已知sinx=3/5,x∈(π/2,π),求【sin(x+y)+sin(x-y)】/【cos（x+y）+cos（x-y）】的值 函数y=sin^2x+2cosx,在[π/3,2π/3]的最小值 y=sin(π/3-π/2x)的周期 y=sin^2(2x+π/3)的导数 求导数 y=sin^2(2x+π/3) 化简y=2sin(x/2+π/3) 判断y=sin(2x+3π/2)奇偶性
