一道用元素法求立体体积习题的探讨

摘要

The main thought of the definite integral is how to indicate the element by approximate method, and getting a precise value by the definite integral. Electing the integral element fiftly is the key of resolving the concrete problem by the method of definite integral. Discussions on one exercises about calculating the three-dimensional volume by the element method are given.%定积分的主要思想是用近似的方法获得微元的表示,然后用积分得到精确值.合理选取积分元素是运用定积分元素法解决问题的关键.对一道用元素法求立体体积的习题进行了探讨.
