4. Two points in the xy plane have Cartesian coordinates
(2.00, #4.00) m and (#3.00, 3.00) m. Determine (a) the
distance between these points and (b) their polar coordinates.
6. If the polar coordinates of the point (x, y) are (r, !), determine
the polar coordinates for the points: (a) (#x, y ),
(b) (#2x, #2y), and (c) (3x, #3y).
