Galadriel is chasing Annatar. Suppose their trajectories are given by the parametric equations re(t) = (-2t, -1 + 2t, 2 + 4t2) and rA(t) = (2t-3,2 - 2t, -1 + 4t2) for 0 t 3. Let CG and CA denote the corresponding space curves. (a) Show that CG and CA intersect in exactly one point, and find the angle between the tangent lines to CG and CA at that point (in radians, to two decimal places). (b) Does Galadriel ever catch Annatar? In other words, is there a time at which Galadriel and Annatar are at the same position? Galadriel is chasing Annatar. Suppose their trajectories are given by the parametric equations ra(t)= (-2t,-1+2t, 2 + 4t2) and rA(t)=(2t-3, 2-2t, -1 + 4t2) for 0 t 3. Let CG and CA denote the corresponding space curves. (a) Show that CG and CA intersect in exactly one point, and find the angle between the tangent lines to Cg and CA at that point (in radians, to two decimal places).
