radius of curvature. n. (Mathematics) the absolute value of the reciprocal of the curvature of a curve at a given point; the radius of a circle the curvature of which is equal to that of the given curve at that point. See also centre of curvature.
The clothoid or double spiral is a curve, whose curvature grows with the distance from the origin. The radius of curvature is opposite proportional to its arc measured from the origin. The parameter form consists of two equations with Fresnel's integrals, which can only be solved approximately.
