在学习椭圆、双曲线的标准方程和几何性质的过程中,一个重要的方面就是要正确理解和掌握它们特有的参数“a、b、c、e”之间关系及几何意义.尤其是会用动态的,变化的观点来看待它们,运用它们的相对关系来解决一些较难题目,就更显得意义不凡.本文举例说明. In the process of learning the elliptic, hyperbolic standard equations and geometric properties, an important aspect is to correctly understand and grasp the relationship between their unique parameters “a, b, c, e” and the geometric meaning. Especially useful. From a dynamic and changing perspective, it is even more significant to use their relative relationships to solve some of the more difficult problems. Here is an example.
