How to find the length of an arc?

In calculus, arc length is the distance along a piece of a curve. Imagine a curved path on a graph; the arc length is the precise measurement of that path between two points. Calculating it involves using a definite integral derived from the Pythagorean theorem, applied to infinitesimally small segments of the curve. This concept is fundamental in fields like physics, engineering, and computer graphics for calculating paths of moving objects or the length of materials.

Frequently Asked Questions about Solving Arc Length Problems with Mathos

The formula for the arc length of a function y = f(x) from x = a to x = b is L = ∫[a, b] √(1 + (dy/dx)²) dx. For a function x = g(y) from y = c to y = d, the formula is L = ∫[c, d] √(1 + (dx/dy)²) dy. Mathos can help you apply the correct formula and solve the integral step-by-step.

Yes, absolutely. Mathos's AI Video Explainer feature is designed for this exact purpose. Simply input your arc length problem, and Mathos will instantly generate a custom animated video that provides a clear, step-by-step walkthrough with a voiceover, just as a live tutor would.
