圆锥曲线的一组漂亮性质

摘要

圆锥曲线是平面解析几何中的重要内容之一，也是学习高等数学、物理、力学和其他科学技术不可缺少的基础知识。本文通过对圆锥曲线一个关于焦点弦及定点性质的大胆猜想和进一步研究，推广得到过圆锥曲线内任意一点的弦与定点相关的一组漂亮性质。%Conic sections is one of the important contents in plane analytic geometry, it＇s also the indispensable basic knowl- edge of the higher mathematics, physics, mechanics and other scientific technology. Through bold guess and further study of a property related to focus chord and fixed point, we promote this property from the focus of the conic sections to any point within the conic sections, and receive a group of beautiful properties related to fixed point.
