摘要
文章对动态正多边形顶点相遇问题,不建立微分方程,而是另辟蹊径,利用微元思想结合极限这一简单工具,以及使用极坐标,给出了此类问题的两种简易解法。
In this paper, the dynamic regular polygon vertices encounter problems, does not establish a differential equation,but another way to infinitesimal the ideological combined limit of this simple tool, as well as the use of polar coordinates, given two simple solution of such problems.
