在学习抛物线的过程中,我们经常会看到抛物线与定点同时出现,其实这里边有很多有意思的结论.在这里我们主要讨论抛物线上弦过定点的问题.问题1过抛物线y2=2px的顶点O(O为坐标原点)作两条互相垂直的弦OA、OB,直线AB是否过定点?若过定点,求出此点的坐标?分析直线AB过定点,从直观上来看, In the process of learning the parabola, we often see the parabola and the fixed point at the same time, in fact, there are a lot of interesting conclusions here we mainly discuss the problem of parabola over fixed point Problem 1 Parabola y2 = 2px vertex O ( O is the origin of the coordinates) for two mutually perpendicular chords OA, OB, whether the straight line AB is over a fixed point? If a fixed point, find the coordinates of this point? Analysis of the line AB over a fixed point, intuitively,
