摘要
不少学生在极限运算中感到一定的困难,文章介绍了关于等价无穷小在极限计算中的代换,特别是1^(∞)、0~0未定型无穷小代换,简化了计算,提高学生运算能力。
Many students feel difficult in the calculation of limit. This article presents the replacement of the same value infinitesimal in calculation of limit, especially the replacement of the 1 ( and 00 indetermination infinitesimal which simplifies calculating so as to improve students' ability to calculate.
