二次曲线外切多角形中有向距离的定值定理
On Some Fixed Value Theorems of Directed Distance for Conic Sections
-
摘要: 文章利用有向距离方法,对二次曲线外切多角形进行研究,得到二次曲线外切多角形中有向距离的几个定理,并指正了有关文献中的错误结论.Abstract: Using the method of directed distances,we make a deep research on conic circumscribed polygons,Several fixed value theorems for directed distances in conic circumscribed polygons are obtained,and two mistaken results in a reference are corrected.
