微积分学L’Hospital法则的推广研究

Study on L'Hospital rule of calculus

本文将一元函数L’Hospital法则进行研究推广,在柯西中值定理的基础上建立多元函数L’Hospital法则,使L’Hospital法则的应用更广泛。

In this paper, we study and extend the L＇ Hospital rule of a variable function, and build the L＇ Hospital rule of muhi- pie-variable functions＂ based on Canchy mean value theorem.
