摘要
阐述了应用Stolz定理求数列极限时应注意的问题,并从Stolz定理与L’Hospital法则相互呼应的角度,指出了∞∞型的L’Hospital法则可改进为*∞型.这些工作,不但扩大了其应用范围,而且还给求极限带来许多方便.
Some problems are presented in applying Stolz theorem to solve limit of sequence. Based on the relation between Stolz theorem and L＇ Hospital rule, L＇ Hospital rule of ∞/∞ type is modified to ＊.∞ type. It correspondent not only enlarges the area of application, but also brings much convenience to solve limit.
