Eccentricity of Hyperbola is the ratio of distances of any point on the Hyperbola from focus and the directrix, or it is the ratio of linear eccentricity and semi transverse axis of the Hyperbola. And is denoted by e. Eccentricity of Hyperbola is usually measured using the Meter for Length. Note that the value of Eccentricity of Hyperbola is always positive. Typically, the value of Eccentricity of Hyperbola is greater than 1.
