We can parametrize the … WebArc lengthis the distance between two points along a section of a curve. Determining the length of an irregular arc segment by approximating the arc segment as connected (straight) line segmentsis also called curve rectification. A rectifiable curvehas a finite number of segments in its rectification (so the curve has a finite length).
