离心率是圆锥曲线重要的几何性质,也是高考考查圆锥曲线的重要题型。关于椭圆、双曲线的离心率问题,主要有两类试题:一类是求解离心率的值,另一类是求解离心率的取值范围。下面举例说明求圆锥曲线离心率的解题策略,以期对同学们有所帮助。一、求离心率的值
Centrifugal rate is an important conic geometry, but also the college entrance examination conic an important question. There are mainly two types of questions about the eccentricity of elliptic and hyperbolic curves: one is the value of solving eccentricity and the other is the range of solving eccentricity. The following example illustrates the solution to the problem of conic eccentricity, in order to help students. First, find the value of eccentricity
