要用定义来做
f(x+π)=f(x)+sinx,0≤x
f(sin^2x)=x/sinx 求f(x)
分段函数f(x)=sinx (x>=0时);f(x)=x^2(x
f(x)=2sinx(0
证明f(x)=x+sinx (0
求f(x)=x-sinx (0
f(x)=x平方sinx,求f'(0),f'(x/2)
f(x)=sinx,求导f('f(x)),f(f'(x)),[f(f(x))]'
设f(x-1)={-sinx/x,x>0;2,x=0;x-1,x
设f(x-1)={-sinx/x,x>0;2,x=0;x-1,x
设函数f(x)连续,lim((f(x)/x)-1/x-(sinx/x^2))=2,f(0)=?
设函数f(x)连续,lim((f(x)/x)-1/x-(sinx/x^2))=2,f(0)=?
设f(x)=sinx f(x+2π)=
f(x)=(sinx)2,求f(x)的导数
f ' (sinx)=cos^2x,求f(x)
f(sinx)=1+cos(2x),求f(x),
设f(x)=x*sinx,求f'' (π/2)
f(x)=sinx(sinx-1)(sinx-2),求f'(0).
