Homework Statement
Find two other pairs of polar coordinates of the given polar coordinate, one with r > 0 and one with r < 0. Then plot the point.
(2, 5π/3)
Homework Equations
I don't there are any.
The Attempt at a Solution
I'm not completely sure of how to do this actually.
I know that we can add 2 pi to the answer to get the coordinates for r > 0 this gives an answer of [itex] (2,\frac{11\pi}{3} [/itex]
But I'm not sure about the r<0 option. Would I simply have to subtract 2 pi from 5 pi/3? In addition, would the r value change to the negative sign?
Thanks for your help.
