摘要
通过把无穷小(大)进行分类,并利用无穷小(大)的种类得到复合函数极限的各种形式,更全面准确地理解复合函数的极限.
We give the definitions of all kinds of infinitesimal (infinity) and then use the infinitesimal (infinity) to get some kinds of limits for compound functions, which make the limits of compound functions understood easily and comprehensively.
