Some Improvement on the Proving of Mean Value Theorem, and L'Hopital's Rule
LI Qing-yuan · Journal of Hebei Engineering Vocational College · 2002
We research careflly on the function used in the proving of Mean Value Theorem and Cauchy' Theorem and we found that we can give another theorem which need less condition and correspondently we can use it to reach the result that we need in the proving of L'Hopital's Rule without the strict condition needed before, and thus we can widen the area where L'Hopital's Rule works.
