WebSep 7, 2024 · In addition to finding the area under a parametric curve, we sometimes need to find the arc length of a parametric curve. In the case of a line segment, arc length is the same as the distance between the endpoints. If a particle travels from point \(A\) to point \(B\) along a curve, then the distance that particle travels is the arc length. WebArc Length = ∫ a b 1 + [f ′ (x)] 2 d x = ∫ −15 15 1 + sinh 2 (x 10) d x.
