对圆锥曲线弦的中点的有关问题,已有不少人作过深入地探讨,但对于点不位于弦的中点时的情况,也许人们认为此类问题解法复杂,同时难以用公式表示,因此,很少有人去研究它,本文将探讨这个问题,并用较简捷方法导出了关于圆锥曲线弦的定比分点问题的有关公式,它有着广泛的应用。 There are many people who have done some in-depth discussions on the midpoint of the conic curve chord, but when the point is not at the midpoint of the chord, people may think that the solution to this type of problem is complicated and difficult to formulate. Therefore, few people will study it. This article will explore this issue and use a simpler method to derive the formula for the problem of the point-of-segment of the conic-curve string. It has a wide range of applications.
