用定义.显然,2π是y=f(x)=(sinx)^3+(cosx)^3的周期.
若存在t:0
y=sin x + sqrt(3)cos x的周期
化简y=sin^2(x)+2sin(x)cos(x)+3cos^2(x)
求y=sin^2(x)+3sin(x)cos(x)-2cos^2(x)的最大值
求y=sin x +2sin x cos x -3cos²x 的周期和值域,
y=sin^2(x)+2sin(x)cos(x)+3cos^2(x)的最值 用向量解
y =(cos^2) x - sin (3^x),求y'
sin^2(x+y)-cos(x+y)sin(x+y)-3cos^2(x+y)的值急用
已知sinx=3/5,x∈(π/2,π),求【sin(x+y)+sin(x-y)】/【cos(x+y)+cos(x-y)】的值
Sin x-sin y=2/3 cos x-cos y=1/2 求cos(x-y)

当cos^2x-cos^2y=√3/2时,求sin(x+y)×sin(x-y)
求下列函数的导数:y=x-sin x/2 cos x/2 y=x^3+3^x
求y=cos(-x^3)+(sin^2)(x^3)+ln(-x)^3的导函数.
sin^3 x -cos^3 x sin^3 x -cos^3 x =(sin x -cos x )(sin^2 x +sin x*cos x +cos^2 x )问下这个是个公式还是什么?怎么样算出来的?
已知Sin(x+y)Cosx-Cos(x-x)Sinx=3/5求tan2y的值
y=sin^2x+cos^2x(x-派/3)的单调增区间
若cos(x+y)cos(x-y)=1/3,则cos^x-sin^y=?^为平方
求y=sin^5x ,y=cos(4x+3) 的导数,
