摘要
指出定积分换元积分法与不定积分换元积分法存在差异,总结并介绍定积分换元积分的几个常用公式,实例说明这些公式的使用方法及换元技巧.
In this paper, we illustrate the difference between the definite integral with substitution and indefinite integral with substitution, and introduce a few of commonly used formulas for definite integral with substitution. With examples, we show the use of substituting techniques of these formulas.
