The arc-length function for a vector-valued function is calculated using the integral formula s(t) = ∫b a‖ ⇀ r ′ (t)‖dt. This formula is valid in both two and three dimensions. The curvature of a curve at a point in either two or three dimensions is defined to be the curvature of the inscribed circle at that point. In other words, the change in arc length can be viewed as a change in the t -domain, scaled by the magnitude of vector ⇀ r′ (t). Example 16.2.2: Evaluating a Line Integral.
