改过啦!
f(x)=sinx+sin(x-π/2）
=sinx+cosx
=2(√2/2*sinx+√2/2cosx)
=2sin(x+45°)
所以,
f(x)的最小正周期：
T=2π/1=2π

f(x)=sinx+sin(x-∏) = sinx - sin(pi - x) = sinx - sinx = 0?

f(x)=sinx+sin(x-π/2）=sinx-cosx=√2sin(x-45°)
所以f(x)的最小正周期：
T=2π/1=2π

f(x)=sinx+sin(x-π/2）
=sinx-cosx
=2(√2/2*sinx-√2/2cosx)
=2sin(x-45°)
T=2π/1=2π

已知函数f(x)=4sinx-2/1+sin²x 证明f(x+2π)=f(x) 已知函数f(x)=sin^2 x,求原函数F(x)?f(x)=sin^2 x=(sinx)^2 已知函数f x =sinx+sin（π/2-x）的周期及值域已知函数f(x)=(sinx+cos)^2-2sin^2x求单调递减区间已知函数F(X)=2sin^2 x-sinx+3的最值已知函数f(x)=[2sin(x+π/3)+sinx]cosx-根号3sin^2x,x属于R,求函数f(x)最小正周期已知函数f(x)=[2sin(x+π/3)+sinx]cosx-根号3sin^2x,x属于R,求函数f(x)最小正周期已知函数f(x)=[2sin(x+π/3)+sinx]cosx-√3sin²x,x∈R求函数f(x)的最小正周期化简cosθsinx-sin(x-θ)+(tanθ-2)sinx-sinθ已知函数f(x)=cosθsinx-sin(x-θ)+(tanθ-2)sinx-sinθ的最小值为0,求sinθ的值. 已知函数f(x)=(sin2x/sinx)+2sin,求函数f(x)的最小正周期? 已知函数f(x)=2√3sinx(x+π/4)cos(x+π/4)-sin(2x+π) 已知函数f(x)=sinx+cos (1)求f(0)的值已知f(x)=sin x+cos x (1)求f（0）的值函数f(x)=sin(sinx+cosx)的最大值是多少? 已知函数f(x)=sinx+sin(x-∏),求f(x)最小正周期sorry!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!~对不起!打错了!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!是:已知函数f(x)=sinx+sin(x-∏/2), 已知函数f(x)=sinx+1/sinx,求其值域已知函数F(X)=2SINX平方+SIN(2X π/6)求函数最小正周期及最大值已知|x|小于等于派/4,求函数f(x)=-sin^2 (x)+sinx+1的最小值已知函数 f(x)=2√3sinx/2cosx/2-(cos²x/2-sin²x/2)
