Quick graphing question, thanks for helping!

I posted the graph in the comments. I need to write the a coordinate in polar form, but make the radius a positive value. I also need to write point B in polar form as well. Thank You, this topic is really confusing. :P

Using Euler's Identity:

$$
\large
Ae^{i	heta}=A(\cos 	heta +i \sin 	heta )
$$

|dw:1434408079892:dw|
Assuming each ring is 1 unit.

Does this make sense?
