摘要
本文研究了积分区域在极坐标变换下的变化规律,进而对直角坐标系下的重积分化成极坐标下的重积分后其累次积分限的确定给出了一种方法.
In this paper we study the variation of integration area under the polar coordinate transfor- mation, and thus we propose a method to determine the repeated integral limit when the Cartesian coordinate system of the multiple integration is changed into polar coordinate system.
