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.
themselves have zero curvature. Large circles should have smaller curvature than small circles which bend more sharply. The (signed) curvature of a curve parametrized by its arc length is the rate of change of direction of the tangent vector. The absolute value of the curvature is a measure of how sharply the curve bends.
