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=
举一反三
- 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,...715af2ac3f81f8.png"]
- f(x)在[0,1]上二阶可导,而且f(0)=f(1)=1,minf(x)=-1,则ξ属于(0,1)使得f’’(ξ)大于等于()。
- 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)
- 设函数f(x)在[0,1]上连续,在(0,1)内可导,且f"(x)<0,则____ A: f(0)<0 B: f(1)>0 C: f(1)>f(0) D: f(1)<f(0)
- 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
