f(x)在[a,b]上连续a
若f(x)在[a,b]上连续,a
设f(x)在[a,b]上连续,a
f(x)在[a,b]上连续a
f(x)在[a,b]上可导,f(x)的导数是否在[a,b]上连续
设函数f(x)在[a,b]上连续,在(a,b)内可导且f'(x)
假设f(x)在区间[a,b]上连续 在(a,b)内可导 且f'(x)
设f(x)在【a,b】上连续,在(a,b)内f''(x)>0,证明:
设f(x)在[a,b]上连续,在(a,b)内可导,f(a)f(b)>0,f(a)f[(a+b)/2]0,f(a)f[(a
证明设f(x)在有限开区间(a,b)内连续,且f(a+) ,f(b-)存在,则f(x)在(a,b)上一致连续.
设f‘(x)在[a,b]上连续,且f(a)=0,证明:|∫b a f(x)dx|
设f(x)在[a,b]上连续,在(a,b)内可导,f(a)f(b)>0,f(a)f[(a+b)/2]
设函数f(x)在[a,b]上连续,在(a,b)可导,且f(a)*f(b)>0,f(a)*f((a+b)/2)
