WebA tangent vector v at t = t 0 t = t 0 is any vector such that, when the tail of the vector is placed at point r (t 0) r (t 0) on the graph, vector v is tangent to curve C. Vector r ′ (t 0) r ′ (t 0) is an example of a tangent vector at point t = t 0. t = t 0. Furthermore, assume that r ′ (t) ≠ 0. r ′ (t) ≠ 0. The principal unit ... WebThe normal vector is defined as any vector which is perpendicular to the curve. Hence the vector you're suggesting which points to the origin would also be described as a normal vector. In this case he is simply taking the outward pointing vector without having disambiguated as one would expect if we were to be strict.
