How Do You Plot and Find Alternate Polar Coordinates?

[shamieh]

Plot the point whose polar coordinates are given. Then find two other pairs of polar coordinates of this point, one with r > 0 and one with r < 0

so I did $$\frac{\pi}{3} + 2\pi = \frac{7\pi}{3} \therefore$$ $$r > 0$$
and did $$\frac{\pi}{3} + \pi = - \frac{4}{3} \pi$$ $$\therefore$$ $$r < 0$$

so i have (2,7pi/3) & (-2, 4pi/3)

Will that work?

Plot the point whose polar coordinates are given.

Where are they given?
