文[1]给出了圆锥曲线的切线与焦半径之间关系的一个统一的性质,读后深受启发,通过探究,便得到了圆锥曲线的另一个有趣的统一性质,兹介绍如下,与大家分享.性质1如图1,已知椭圆C:x2a2+y2b2=1(a>b>0)的焦点为F,椭圆C上一点P(不是左右顶点)处的切线为l,直线l与x轴交于点T,则 [1] gives a uniform property of the relationship between the tangent of the conic curve and the focal radius. After reading it, it is inspired by the fact that another interesting unifying property of the conic is obtained by probing, as follows, and 1, the focal point of the ellipse C: x2a2 + y2b2 = 1 (a> b> 0) is known as F, the tangent at the point P (not the left and right vertices) on the ellipse C is l, and the straight lines l and x-axis at the point T, then
