关于几何中的点与点之间的距离问题,是研究点与点、点与线、点与面、线与线、线与面以及面与面的关系的最基本的内容,而距离的最值问题又是考试中常涉及的知识点,且在实际生活中具有广泛的应用价值。以下就圆锥曲线中曲线上的点到一焦点和定点的距离之和的最值问题予以总结,以便在解答有关选择题和填空题时直接引用,供大家参考。
The question about the distance between points and points in geometry is the most basic content of the relationship between points and points, points and lines, points and surfaces, lines and lines, lines and surfaces, and surfaces and surfaces, and the distance The value problem is often the point of knowledge involved in the exam, and has a wide range of practical value. The following is a summary of the maximum value of the sum of the distances from the point on the curve in the curve to the distance between the fixed point and the fixed point so as to be used as a reference when answering the questions on multiple choice and blank fill.
