ETYM Cf. French excentricité.
1. Strange and unconventional behavior.
2. A circularity that has a different center or deviates from a circular path.
3. (Geometry) A ratio describing the shape of a conic section; the ratio of the distance between the foci to the length of the major axis.
In geometry, a property of a conic section (circle, ellipse, parabola, or hyperbola). It is the distance of any point on the curve from a fixed point (the focus) divided by the distance of that point from a fixed line (the directrix). A circle has an eccentricity of zero; for an ellipse it is less than one; for a parabola it is equal to one; and for a hyperbola it is greater than one. + prikaži više
