    The eccentricity of an ellipse is, most simply, the ratio of the linear eccentricity c (distance between the center of the ellipse and each focus) to the length of the semimajor axis a
  • Eccentricity - Math is Fun
    Eccentricity is often shown as the letter e (not to be confused with Euler's number "e", they are totally different) We can define eccentricity as the ratio of distances from any point P on the curve to a fixed point (the focus) and a fixed line (the directrix): eccentricity e = distance from P to Focus distance from P to Directrix
