Hi, I have been representing complex numbers in graphical form in school recently. My teacher was telling me about a graph which shows all 4 quadrants and basically shows you what each quadrant is in terms of pi. Hopefully you understand what I mean, I have been looking on the internet for this graph but I can't seem to find it. If you know somewhere where it is, can you please tell me? Thanks. I need it so I can see if I have to minus pi or add it.
