离心率是圆锥曲线中的一项重要内容,它是描述曲线形状的重要参数,求离心率的范围关键在于建立与离心率有关的不等式,本文就如何建立不等关系求离心率范围作一点探讨,供大家参考。
The eccentricity is an important part of the conic curve. It is an important parameter to describe the shape of the curve. The key to finding the eccentricity range is to establish the inequality related to the eccentricity. This article discusses how to establish the range of eccentricity for the unequal relationship. ,For reference.
