(4 points) If llr(t)ll = c, where c is a constant, at what angle do r(t) and r(t) intersect? (hint: Differentiate both sides of llr), then take the square root and use part 3. (2 points) From the angle you found in part (b) under the hypotheses that the norm is constant, does this imply that r(t) and r(t) are parallel, orthogonal, or neither?
