关于二重积分中定限问题的讨论

Discussion on the Definite Dual Integral

二重积分中,如果确定积分的上、下限,有时是一个比较复杂的问题,因此如何针对题目中所给定的条件,综合运用数学分析中所学的知识去解题是非常重要的,这里归纳了几种方法,可供参考。

It is sometimes difficult to definite the integral's upper bound and lower bound. So it is of importance to solve the problems in terms with the given conditions by comprehensively using the knowledge learned in mathematical analysis, Here are some methods of solving such problems for your reference.
