分部积分中如何选择u和dv

Rightly Select u and dv During the Subsection Integral

对由五种基本初等函数构成的不定积分的计算方法进行了探讨,提出了选取u和dv时应遵循的一般原则.

Integration by parts has been most fundamental and commonly used means during operating indefinite integration. Rightly selection the u and dv is the most important step during operating indefinite integral by subsection integral. we have discussed the calculational methods of indefinite integral which constituted by five kinds of basic elementary function. At same time, basic principle we have to follow during rightly selection u and dv have been put forward.
