椭圆

椭圆和它的某些数学性质。
一个平面切截一个圆锥面得到的椭圆。
在正规位置上的椭圆的参数方程。参数 t 是蓝线对于 X-轴的角度。
椭圆的极坐标,原点在 F1

在数学中,椭圆是平面上到两个固定点的距离之和为常数的点之轨迹

根据该定义,可以用手绘椭圆:先准备一条线,将这条线的两端各绑在固定的点上(这两个点就当作是椭圆的两个焦点);取一支笔,用笔尖将线绷紧,这时候两个点和笔就形成了一个三角形(的两边);然后左右移动笔尖拉着线开始作图,持续地使线绷紧,最后就可以完成一个椭圆的图形了。

  • 由于两个固定点之间的距离也是一定的,所以可以省去绑在点上这一步骤而改将线绑成环状,然后以笔尖和这两个焦点将线绷直即可。下同。

Ellipse 椭圆

An ellipse obtained as the intersection of a cone with an inclined plane.
The ellipse and some of its mathematical properties.
The distance traveled from one focus to another, via some point on the ellipse, is the same regardless of the point selected.
Drawing an ellipse with two pins, a loop, and a pen

In mathematics, an ellipse is a curve on a plane that surrounds two focal points such that the sum of the distances to the two focal points is constant for every point on the curve. As such, it is a generalization of a circle, which is a special type of an ellipse that has both focal points at the same location. The shape of an ellipse (how 'elongated' it is) is represented by its eccentricity, which for an ellipse can be any number from 0 (the limiting case of a circle) to arbitrarily close to but less than 1.
