## What is eccentricity and how it is calculated for an ellipse ?

The eccentricity of an ellipse is, most simply, the ratio of the distance c between the center of the ellipse and each focus to the length of the semimajor axis a. It is calculated by the formula e = √ 1 - (a2 / b2 ) where e is the eccentricity of an ellipse a is the minor axis of an ellipse and b is the major axis of an ellipse.

### FAQ

What is Eccentricity of an ellipse (b>a)?
Eccentricity of an ellipse (b>a) is a non-negative real number that uniquely characterizes its shape and is represented as e=sqrt(1-((b)^2/(a)^2)) or Eccentricity=sqrt(1-((Minor axis)^2/(Major axis)^2)). Major axis is the line segment that crosses both the focal points of the ellipse and Minor axis is the line segment that is perpendicular to the major axis and intersects at the center of the ellipse.
How to calculate Eccentricity of an ellipse (b>a)?
Eccentricity of an ellipse (b>a) is a non-negative real number that uniquely characterizes its shape is calculated using Eccentricity=sqrt(1-((Minor axis)^2/(Major axis)^2)). To calculate Eccentricity of an ellipse (b>a), you need Major axis (a) and Minor axis (b). With our tool, you need to enter the respective value for Major axis and Minor axis and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
How many ways are there to calculate Eccentricity?
In this formula, Eccentricity uses Major axis and Minor axis. We can use 4 other way(s) to calculate the same, which is/are as follows -
• Eccentricity=sqrt(1-((Minor axis)^2/(Major axis)^2))
• Eccentricity=(Linear Eccentricity)/Major axis
• Eccentricity=sqrt(1+((Semi-minor axis)^2/(Semi-major axis)^2))
• Eccentricity=Linear Eccentricity/Major axis
