y=sin(x+π/6）sin(x-π/6）的最小周期是y=sin(x+π/6）sin(x-π/6）的最小周期是y=sin(x+π/6）sin(x-π/6）的最小周期是积化和差y=sin(x+π/6)
y=sin(x+π /6）sin(x-π/6）的最小周期是
y=sin(x+π /6）sin(x-π/6）的最小周期是
y=sin(x+π /6）sin(x-π/6）的最小周期是
积化和差
y=sin(x+π/6)sin(x-π/6)
=[cos(x+π/6-x+π/6)-cos(x+π/6+x-π/6)]/2
=[cos(π/3)-cos(2x)]/2
=1/4-cos2x/2
故T=2π/2=π
如果不懂,请Hi我,祝学习愉快!

y=sin(x+π /6）sin(x-π/6）的最小周期是
判断单调性 y=sin(x-π/6) y=sin(-2x+π/3)
y=sin（x+π/6)如何移动得到y=sin(2x+π/3）
y=sin（x+π/6)如何移动得到y=sin(2x+π/3）用两种方法啊
Y=sin(x+6/π)+sin(x-6/π)+cosx
函数y=2sin(π/3-X)+sin(π/6+X)的最大值
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
函数y=4sin(x+π/6)+3sin(π/3-x)的最大值是多少
y=sin(x-π/6)sin(x+π/3)最小正周期
已知x+y+z=π,证明sin(x+y)+sin(y+z)+sin(z+x)≥sin2x+sin2y+sin2z
y=sin(x+π/3)周期
y=|sinπx|的周期
y=sin(x-π/6) x∈【0,π】函数y=sin（x-π/6）,x∈【0,π】的值域是
y=2sin(x/2+π/6),x属于R y=-6sin(2x-π/3）,x属于R 写出振幅,周期,初相
周期 最值 单调区间y=sin(2x+π/3) y=2sin（2x+π/6）-2 y=sin（π/3-2x） y=tan（π/3-2x）
已知sinx=3/5,x∈(π/2,π),求【sin(x+y)+sin(x-y)】/【cos（x+y）+cos（x-y）】的值
求证sin²x-sin²y=sin(x+y)sin(x-y)
