SOLUTION: Other pairs of coordinates that name the same polar coordinate: (3, 30�)

Question 1032927: Other pairs of coordinates that name the same polar coordinate: (3, 30�)
Answer by Edwin McCravy(20060) (Show Source): You can put this solution on YOUR website!

(3, 30�)

1. You may add or subtract any multiple of 360�
to the angle q and get a new 
pair of polar coordinates for the same point.

(3, 390�), (3, -330�), etc.

2. Or you may multiply the radius r, in this case 3,
by -1 and add or subtract any ODD multiple of 180� and
get a new pair of polar coordinates for the same point


(-3,210�), (-3,-150�), etc.
