关于型的L′Hospital法则的一个改进

The Improvement of L′Hospital's Ruler〔〕

本文对现行的数学分析、微积分及其高等数学的教材中的 ∞∞ 型的 L′Hospital法则进行了一个改进 ,论证了该法则在无须考虑分子是否趋于∞的条件时 ,仍旧成立 ,利用了这个减弱了的 ∞∞ 型的

In this paper, we discuss L′Hospital's ruler ∞∞. We've learned it in Mathematical Analysis. Calculus and Higher Mathematics, where required numerator and denominator both tend to ∞. But here. We don't have to consider if namerator tend to ∞. While the L′Hospital's ruler is still right. Use this result, we can deal with many limit's question in simple way.
