数学来源于生活 ,又应用于生活 .圆锥曲线是我们生活中常见的曲线 ,如何利用圆锥曲线方程来解决生活中的实际问题 ,本文举例以说明 .例 1 太平洋上有A、B两个岛屿 ,B岛在A岛正东 40 0海里处 .经多年观察研究发现 ,某种鱼群洄游的路线基本上是一个椭圆 ,其焦点恰好是A、B两岛 .
Mathematics comes from life and is applied to life. Conic curves are common curves in our lives. How to use conic curve equations to solve practical problems in life. This article gives an example to illustrate. Example 1 There are two islands A and B in the Pacific Ocean. Island B is 400 kilometers east of A Island. After years of observation and research, it has been found that the route of a fish school is basically an ellipse. Its focus is exactly the two islands A and B.
