y=sin(x+π/6)+sin(x-π/6)+cosx ,x∈[-π/2,π/2]的值域
y=sin(x+π/6)+sin(x-π/6)+cosx ,x∈[-π/2,π/2]的值域

【-2,2】.
先用三角函数和差公式展开.
然后用三角函数的统一形式化简,最后得到:
y=2sin(x+π/6)
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)
