Well, I'll start to post questions at Math.SE. Two frustrated questions in a row.
I'd like to have met Math.SE from the start


Thank you for your advices. ]]> Noah Snyder comments on "How are the non-real roots of a quadratic function represented in RxR" (16315) http://mathoverflow.tqft.net/discussion/1154/how-are-the-nonreal-roots-of-a-quadratic-function-represented-in-rxr/?Focus=16315#Comment_16315 http://mathoverflow.tqft.net/discussion/1154/how-are-the-nonreal-roots-of-a-quadratic-function-represented-in-rxr/?Focus=16315#Comment_16315 Sat, 01 Oct 2011 09:44:29 -0700 Noah Snyder Quid and Todd are exactly right. Math.SE is a much better site for you to use. With your level of background there is basically no question you could ask which would not get closed here. However, this is nothing to be ashamed of, Math.SE is a great site and there's nothing wrong with being a beginner in a subject.

In fact, based on this question alone, I urge that you not post any more questions at MO or at meta until you have learned a whole lot more. You should use math.stackexchange.com in the meantime.

In general and roughly speaking the background in mathematics that is assumed on MO is about five years of university-education in mathematics. However, there is a very similar site http://math.stackexchange.com/ that welcomes mathematical question on all levels. On that other site I think your question is suitable.

Since you are already here a short remark: you can read about geometric interpretations of complex numbers for example on the wikipidea page Compex Plane ; also called Argand Plane.

Do they have any meaning in the Cartesian plane? I they do, what is the explanation?

What do you think? Is it acceptable?

I'm going to post in meta.mo everytime I need to ask something on MO ]]>
