y=sin(x-π/6)sin(x+π/3)最小正周期y=sin(x-π/6)sin(x+π/3)最小正周期y=sin(x-π/6)sin(x+π/3)最小正周期y=sin(x-π/6)sin(x+π
y=sin(x-π/6)sin(x+π/3)最小正周期
y=sin(x-π/6)sin(x+π/3)最小正周期
y=sin(x-π/6)sin(x+π/3)最小正周期
y=sin(x-π/6)sin(x+π/3)
=-cos(x-π/6+π/2)sin(x+π/3)
=-cos(x+π/3)sin(x+π/3)
=-sin(2x+2π/3)/2
T=2π/2=π
y=sin(x-π/6)sin(x+π/3)
=sin(x-π/6)*cos[π/2-(x-π/3)]
=sin(x-π/6)cos(π/6-x)
=sin(x-π/6)cos(x-π/6)
=1/2sin(2x-π/3)
所以，最小正周期T=2 π/2=π
判断单调性 y=sin(x-π/6) y=sin(-2x+π/3)
Y=sin(x+6/π)+sin(x-6/π)+cosx
y=sin(x+π /6）sin(x-π/6）的最小周期是
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
求证sin²x-sin²y=sin(x+y)sin(x-y)
