判断单调性 y=sin(x-π/6) y=sin(-2x+π/3)
y=2sin三分之一x y=4sin(x-π/3) y=sin(2x+π/6) y=3sin(1/2x-π/4) 的周期各是多少,
1.y=x*e^(2x) 2.y=(sin(2x))/x 3.y=sin(3x+(π/3))怎么求导数!
当cos^2x-cos^2y=√3/2时,求sin(x+y)×sin(x-y)
y=x^3sin^2x是奇函数还是偶函数还有y=x^cosx、y=5sin(3x-π/4)
1.y=sin(-X+π/6)2.y=cos(-2X+π/3)
求下列函数周期 y=3sin(x/4) x属于Ry=2sin(2x-π/6)
3sin^2x+-2sin^2y=2sinx sin^2x+-sin^2y=?
y=√3sin(1/2x-π/4) 最值 X=?Y max=
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
证明sinx+siny+sinz-sin(x+y+z)=4sin((x+y)/2)sin((x+y)/2)sin((x+y)/2)
y=2cos(x/4+ π/3)-3sin(x- π/4)y=sin(4x- π/3)-cos(3x+π/2)
y =(cos^2) x - sin (3^x),求y'
已知sinx=3/5,x∈(π/2,π),求【sin(x+y)+sin(x-y)】/【cos(x+y)+cos(x-y)】的值
