有趣的数学规律
椭圆 双曲线 抛物线都叫圆锥曲线 它们跟圆锥有着怎样的关系?
他们都是圆锥与平面在不同姿势下交配的产物.

离心率
完美的圆轨离心率为0,椭圆的离线率在0到1之间,也就是说这个范围内,离心率越大,轨道就椭圆的越厉害(长短半轴差距越大.)
这里有很多天体的知识点
圆轨道：e=0\,\!,
椭圆轨道：{\displaystyle 0<e<1\,\!},
抛物线轨道：e=1\,\!,
双曲线轨道：e>1\,\!,

指数和对数
y = a^x
a是底数
x是指数
- 定义域R通俗来讲就是 一个未知数的范围
如: y=2^(3-x)
定义域就是x的取值范围
指数函数的定义域就是R也就是全体实数
所以3-x的范围是全体实数
所以的定义域就是全体实数R
