摘要
论述了分部积分法求类似这类积分:∫sin mx•cos nxdx的方法;又论述了求定积分用到的二重积分法与含参数积分法,这些问题的探索对积分方法的学习具有一定指导意义.
This paper gave a method to solve∫sin mx•cos nxdx by integral subsection integration and then discussed the double integral method and parametric integral method.The discussion of these problems had certain guiding significance for the study of integral method.
