Eccentricity (mathematics) - Wikipedia
The eccentricity of an ellipse is strictly less than 1. When circles (which have eccentricity 0) are counted as ellipses, the eccentricity of an ellipse is greater than or equal to 0; if circles are given a special category and are excluded from the category of ellipses, then the eccentricity of an ellipse is strictly greater than 0. … 展开
In mathematics, the eccentricity of a conic section is a non-negative real number that uniquely characterizes its shape.
One can think of the eccentricity as a measure of how much a conic section deviates from being … 展开The eccentricity is sometimes called the first eccentricity to distinguish it from the second eccentricity and third eccentricity defined for ellipses (see below). The eccentricity is also sometimes called the numerical eccentricity.
In the case of ellipses … 展开Standard form
Here, for the ellipse and the hyperbola, a is the length of the semi-major axis and b is the length of the semi … 展开The eccentricity of a hyperbola can be any real number greater than 1, with no upper bound. The eccentricity of a rectangular hyperbola is $${\displaystyle {\sqrt {2}}}$$. 展开
Any conic section can be defined as the locus of points whose distances to a point (the focus) and a line (the directrix) are in a constant ratio. That ratio is called the eccentricity, commonly denoted as e.
The eccentricity can also be defined in terms of the intersection … 展开Three notational conventions are in common use:
1. e for the eccentricity and c for the linear eccentricity.
2. ε for the eccentricity and e for the linear eccentricity.
3. e or ϵ< for … 展开CC-BY-SA 许可证中的维基百科文本 Eccentricity - Math is Fun
Eccentricity: how much a conic section (a circle, ellipse, parabola or hyperbola) varies from being circular. A circle has an eccentricity of zero , so the eccentricity shows you how "un-circular" the curve is.
