In mathematics, the eccentricity, denoted e or {\displaystyle \varepsilon } \varepsilon, is a parameter associated with every conic section. It can be thought of as a measure of how much the conic section deviates from being circular. In particular, The eccentricity of a circle is zero. The eccentricity of an ellipse which is not a circle is greater than zero but less than 1. The eccentricity of a parabola is 1. The eccentricity of a hyperbola is greater than 1. The eccentricity of a line is infinite. Furthermore, two conic sections are similar (identically shaped) if and only if they have the same eccentricity. read less

A conic section, or conic is the locus of a point which moves in a plane so that its distance from a fixed point is in a constant ratio to its perpendicular distance from a fixed straight line and this constant ratio is called eccentricity denoted by ‘e’. Value of ‘e’ Types of conics e = 1 Parabola 0...
