椭圆中的性质很多,大多是针对焦半径和焦点弦的某种形式出现的定值问题的研究.对于直线和椭圆相交或相切状态下的简单适用的结果不多.笔者曾写过一篇关于“直线和椭圆相交状态下的一个通用性质”[1]的文章,对标准方程下焦点三角形的面积和坐标间的对应关系进行了一点初步的研究.近来通过直线和椭圆相切状态下的有关计算,得到下面结论,期待能对实践应用有所帮助.
Many properties of the ellipse, mostly focus on the focus radius and the focus of some form of value of the value of the problem. For straight lines and elliptical intersection or tangent state of the simple application of the results is small. A little preliminary study on the correspondence between the area and the coordinates of the focal triangle under the standard equation has been carried out on the article “A General Property under the Intersection of Lines and Ellipses”, [1] Under the relevant calculations, get the following conclusions, looking forward to the practical application of help.
