Natural parameter
From Encyclopedia of Mathematics
on a rectifiable curve
A parameter 
for a curve 
with parametric representation 
such that the arc length on the curve between two points 
and 
is equal to 
. The parametrization of a curve by the natural parameter is known as its natural parametrization. The natural parametrization of a 
-times differentiable (analytic) curve with no singular points is also 
times differentiable (analytic).
