EXERCISE 1.63. The unsigned curvature of a plane curve γ(t)-(x(t), v(t)) can be computed with Proposition 1.46 by considering it to have a vanishing third component function: γ(t) (x(t),y(t),0). Use this method to compute the curvature function of the parabola y(t) (t, t2). How can the signed curvature be determined from this approach? EXERCISE 1.63.
