C3D.1 Present a careful argument (preferably using a pic- ture) answering each of the questions below. (a) Under what circumstances is 1 1 - 0 + 612 (b) Under what circumstances is ju - .= 0? (c) Can u - w| ever be greater than in + m? (d) Can i - to ] ever be greater than ju - ? (e) Can fi - to ever be greater than jo - (to) (assuming the latter is positive)? (Hint. Suppose the longer vector is it. Imagine that we place the tail of if at the tip of . The tip of if must then die somewhere on a ends of radius forj around the tip of a. Drawing a diagram of this may help you visualize all of the possible relationships between i and why
