# Arc Length Approximation

Requires a Wolfram Notebook System

Interact on desktop, mobile and cloud with the free Wolfram Player or other Wolfram Language products.

This Demonstration is designed to introduce calculus students to the idea of a limit. Adding the lengths of a number of line segments with endpoints on a curve gives successively better approximations of the length of the curve as increases toward infinity, as long as the length of the largest line segment tends to zero.
