y=sin(2x-π/3) x∈(π/2,π)求值域

已知sinx=3/5,x∈(π/2,π),求【sin(x+y)+sin(x-y)】/【cos（x+y）+cos（x-y）】的值 判断单调性 y=sin(x-π/6) y=sin(-2x+π/3) 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 1.y=x*e^(2x) 2.y=(sin(2x))/x 3.y=sin(3x+(π/3))怎么求导数! 设函数 f(x)=sin(2x+y),(-π y=sin(2x-π/3) x∈(π/2,π)求值域 y=sin(2x+π/6),x∈[π/4,3π/4]求值域 求函数的值域y=sin(2x+π/3),x∈(-π/6,π) y=sin(π/3-π/2x)的周期 求y=sin(2x+π/6)x∈(0,π/3)的值域 y=sin(x+π/3)(其中x∈[0,2π])的单调递增区间 y=sin(x+π/6)+sin(x-π/6)+cosx ,x∈[-π/2,π/2]的值域 y=sin^2x+sin (π/2-x)+3sin^2(3π/2-x)若tanx=0.5.求y值;若x∈【0,π/2】求y值域 y=sin^2(2x+π/3)的导数
