Eccentricity Formula
The following formula is used to calculate the eccentricity of a shape.
e = c / a
- Where e is the eccentricity
- c is the distance from the center to the focus point
- a is the distance from the center to the vertex
Eccentricity Definition
Eccentricity is defined as the ratio of the distance from the center to a focus point to the distance from the center to the vertex.
Eccentricity Example
How to calculate eccentricity?
- First, measure the distance c.
C is the measure of the distance from the center of the ellipse to the focus point.
- Next, measure the distance a.
A is the measure of the distance between the center to the vertex.
- Finally, calculate the eccentricity.
Divide the value c by the value a to calculate the eccentricity of the shape.
FAQ
Eccentricity is a measure of the ratio of the locus of a point focus and the distance on the line to that point. In other words, it’s a measure of how much a particular shape, typically and ellipse, varies from a prefect circle. The greater the eccentricity the greater the variation and more oval shape it is.
