a. The ratio of the change in the angle of a tangent that moves over a given arc to the length of the arc.
b. The limit of this ratio as the length of the arc approaches zero.
c. The reciprocal of the radius of a circle.
3. Medicine A curving or bending, especially an abnormal one: curvature of the spine.
