函数极限的几种求解方法腾飞上海电机学院文理学院，上海 201306摘要：函数极限是高等数学中一个重要内容，而对于函数极限的求法也有很多种。
本文主要归纳了几种常用求函数极限的方法：利用定义，四则运算法则，左右极限，等价无穷小替换，洛必达法则。
关键词：函数极限；等价无穷小替换；洛必达法则 Severalmethods of solving the functionlimit Teng Fei (School ofArts and Sciences, Shanghai Dianji University, Shanghai 201306, China)极限是研究函数的基本工具，也是贯穿高等数学始终的重要内容。
掌握求函数极限的方法是学好高等数学的关键。
然而求函数极限的方法很多，又非常的灵活，这都给初学者带来了很大的困惑，同时也影响后续课程的学习。
因此，本文将总结一些函数极限的求解方法。
1.利用定义求函数极限例1 证明证明，要证，当时，有。
只要证。
，取，使得当时，有。
2.利用四则运算法则求函数极限例2解当时，分子，分母的极限均为零，而且它们不可以分解因式，但可以分子有理化。
=注: 这种方法主要应用于一些简单函数的和，乘积，商的极限，通常情况下，要使用这些法则，往往要根据具体情况先对函数的某些恒等变形或化简。
1.利用左右极限求函数极限例3 设，求。
解，由。
1.利用等价无穷小替换求函数极限例4 计算解，当时，，，。
注在利用等价无穷小做替换时，只能在乘积形式中代换，和差形式要转化成乘积形式。
1.利用洛必达法则求函数极限例5 求解注利用洛必达法则求函数极限，每次分别求导后都要判断此式是否满足洛必达法则的条件，满足才能继续，不满足则不能应用洛必达法则。
以上几种方法是求函数极限的几种常用方法。
此外，还有很多其它求函数极限的方法，如，夹逼准则，单调有界原理，泰勒展式等方法。
很多复杂问题需要几种方法联合使用。
总之，求函数极限的方法很多，也很灵活。

2.2 无穷小量与无穷大量
函数(包括数列)的变化趋势，有两种重要情况，一是趋于0，趋 于0 的量叫无穷小量；一是趋于，趋于 的量叫无穷大量。对无 穷小量和无穷大量的分析，将给极限的计算带来方便。
2.2.1 无穷小量
解： lim f (x) lim 2x2 2 10

例2.1.2． f (x) sin x , 求 lim f (x)。 x0

例2.1.2．f (x) c , 求 lim f (x) 。 x2
解： lim f (x) lim c c ,见图2.1-2。
=0
证毕
§2. 3
在使用极限的四则运算法则时，应注意其使用的条件，那就是
lim f (x) , lim g(x) 都存在，以及商的极限中，lim g(x) 0 。忽视
无穷小量的倒数，是无穷大量。
定理 2.2.3：
lim f (x) A lim f (x) A 0
xx0
xx0
符号“”读作“当且仅当”。
于是，若 lim f (x) A, 则
x x0
f (x) = A +
其中， = f (x) –A(当x x0时)为无穷小量。
利用这一性质分析极限，有些情况下是很方便的。
定义 2.1.3 若随着 | x | 无限变大，f (x)无限趋 于常数A，见图2.1-6。 则称当时，f (x)的极限是A，记为
当，f (x)A 或 lim f (x) A
