精品文档---下载后可任意编辑 等价无穷小量具有很好的性质,灵活运用这些性质,无论是在求极限的运算中,还是在正项级数的敛散性推断中,都可取到预想不到的效果,能达到罗比塔法则所不能取代的作用
通过举例,对比了不同情况下等价无穷小量的应用以及在应用过程中应注意的一些性质条件,不仅使这些原本复杂的问题简单化,而且可避开出现错误地应用等价无穷小量
关键词:等价无穷小量;极限;洛必达法则;比较审敛法;优越性ABSTRACTEquivalent Infinitesimal have good characters,both in operation of test for Limit and determine whether the positive series converges or diverges,if these quality that apply flexibly can obtain more effect,theeffection can not be replace by L'Hospital Rule
This paper give examples and compare some instance to pay attention to condition in application of Equivalent Limit,so the question can be simply and avoid error in application
