f(x)在〔0,1〕上连续.f(0)=f(1)证明存在x使f(x)=f(x+0.5)
举一反三
- 设f(x)在【0,1】上连续,(0,1)可导.f(0)=0,f(1)=1.证明:存在C属于(0,1)使f(c)=1-c
- 设函数f(x)在[0,1]上连续,在(0,1)上可导,且f'(x)>0,则A.()f(0)<0()B.()f(1)>0()C.()f(1)>f(0)()D.()f(1)
- 设f(x)在[0,1]上二阶可导,且f(0)=f"(0)=f(1)=f"(1)=0.证明:方程f"(x)=f(x)=0在(0,1)内有根.
- f(x)在[0,1]上有连续的二阶导数,f(0)=f(1)=0,任意x属于[0,1],使得f(x)不等于0,则=
- 设f(x)在[0,1]上二阶连续可导,且f’(0)=f’(1).证明:存在ξ∈(0,1),使得
