WebJan 24, 2024 · This formula is known as the arc length formula, and it is a special case of the more general line integral. In this formula, dx/dt and dy/dt are the partial derivatives of x and y with respect to t, and dt is the change in t. The definite integral calculates the sum of the squares of the magnitudes of the velocity vectors along the curve.
