on a rectifiable curve

A parameter s for a curve γ with parametric representation r=r(s) such that the arc length on the curve between two points r(s1) and r(s2) is equal to |s1s2|. The parametrization of a curve by the natural parameter is known as its natural parametrization. The natural parametrization of a k-times differentiable (analytic) curve with no singular points is also k times differentiable (analytic).
