WebA parametrization of a curve is a map ~r(t) = hx(t),y(t)i from a parameter interval R = [a,b] to the plane. The functions x(t),y(t) are called coordinate functions. The image of the … WebDec 28, 2024 · This leads to an important concept: measuring the rate of change of the unit tangent vector with respect to arc length gives us a measurement of curvature. Definition 11.5.1: Curvature. Let ⇀ r(s) be a vector-valued function where s is the arc length parameter. The curvature κ of the graph of ⇀ r(s) is.
