'''Arclength''' is the [[mathematics|mathematical]] length of a curve.  The length can be found by selecting a finite number of points along the curve and connecting the points with straight lines.  The sum of the line segments can give the length of the arc.  The more points used, the closer the approximation to the curve.

The length can be approximated by selecting a finite number of points along the curve and connecting the points with straight lines.  The sum of the line segments can give a lower estimate for the length of the arc.  The more points used, the closer the approximation to the curve. Technically, the arclength is the [[supremum]] of all such sums.
