浅谈几类特殊初等函数的积分法

The Integral Way of Several Special Elementary Functions

以有理函数的积分为基础,初步探讨将三角函数不仅能通过万能代换而且用其他形式,也可转化为有理函数的积分;对于积分较为困难的无理函数,其关键在于如何去掉根号,解决了几种特殊情况。

Based on the integral of the rational function, this paper initially probes into turning the trigono- metric function into the integral of the rational function by the all - purpose replacement and other forms. It is difficult for the irrational function to be integral, and the key is how to remove the radical sign.
