| − | '''Arclength''' is the [[mathematical]] length of a [[curve]], i.e. the distance that would be registered if one traveled along the curve as if it were a road.

| − | 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, represented as an [[integral]].
