$(-3, -210^{\circ})$ (a) We can see the point plotted on the graph below. (b) We can write two other pairs of polar coordinates for this point: $(3, 330^{\circ})$ $(-3, 150^{\circ})$ (c) $(x,y) = (\frac{3\sqrt{3}}{2},-\frac{3}{2})$
$(-3, -210^{\circ})$ (a) We can see the point plotted on the graph below. (b) We can write two other pairs of polar coordinates for this point: $(3, 330^{\circ})$ $(-3, 150^{\circ})$ (c) We can find the rectangular coordinates: $r = 3$ and $\theta = 330^{\circ}$ $(x,y) = (r~cos~\theta, r~sin~\theta)$ $(x,y) = (3~cos~330^{\circ}, 3~sin~330^{\circ})$ $(x,y) = (\frac{3\sqrt{3}}{2},-\frac{3}{2})$
