一种新的函数分类方法——分部积分法关键函数的确定原则

As one of the two basic approaches in indefinite integral calculations, integration by parts functions with a key in the proper choice of u and v ; especially the repetition of such choices keeps the students groping in the dark.

分部积分法是不定积分计算中两种重要的基本方法之一,它的关键是正确地选择u,v',尤其是需要多次选择u,v'时,学生盲目性很大,因此,在分部积分法的教学中提出两点改革。

With integration by parts as a guide,this paper further gives quick accurate and new methods for solving integrals such as ∫x ne ax d x and ∫x n sin ax d x,and presents a general conclusions expressed by formula.

本文以分部积分法为导向，进一步给出求解如∫ｘｎｅａｘｄｘ，∫ｘｎｓｉｎａｘｄｘ等类型积分的快速而又准确的新方法，并且给出公式性的一般结论。
