一种新的函数分类方法——分部积分法关键函数的确定原则

A New Classification Methods for Functions: The Confirm Principles of Key Function in Integration by Parts

在高等数学的不定积分中,针对学生对分部积分法中u的确定及哪部分为u感到的困难.本文对关键函数u的确定提出了一种新的分类方法.

Many students feel difficult when determining the u of the integration by parts in the indefinite integral of the higher mathematics. The question of how to determine the u and of which part is determined is discussed by a new classification method provided to determine the key function u in the article.
