Hi Everyone,
My textbook says that in order to find additional polar coordinates, 'a point represented by (r, θ) can also be represented by (r, θ+2nπ) and (-r, θ+(2n+1)π), where n=any whole number. I have no problem finding an additional polar coordinate using the first equation, (r, θ+2nπ), but I can never get the coordinates right using the second equation. To be honest, I don't really understand what 'θ+(2n+1)π' is asking me to do because everytime I plug in n and add the whole thing to θ, I get the wrong answer. Does anyone know what I'm doing wrong/have any insight?
Thank you in advance for your help.
