请看下面一道高考题:例(2014年浙江理科卷)设直线x-3y+m=0(m≠0)与双曲线x2/a2-y2/b2=1(a>0,b>0)的两条渐进线分别交于点A,B,若点P(m,0)满足|PA|=|PB|,则该双曲线的离心率是.赏析应该说,对大多数同学而言,这道题不算难,所以我们这里并不想就这道题本身作太多的讨论.本文讨论的重点是想将高考卷中曾经出现的几个有关问题作统一 Take a look at the following entrance exam questions: Example (Zhejiang Science Volume 2014) Suppose the straight line x-3y + m = 0 (m ≠ 0) and the hyperbola x2 / a2-y2 / b2 = 1 (a> 0, b> 0) The two asymptotic lines are respectively intersected with points A and B. If the point P (m, 0) satisfies | PA | = | PB |, the eccentricity of the hyperbola is 0. Appreciation It should be said that for most of the students, This question is not too difficult, so we do not want to discuss too much about the issue itself.This article discusses the key point is to want to unify the several related questions that appeared in the entrance exam papers
