Imaginary Numbers (1 Viewer)

[blackfireweb]

Hey guys, I'm sorry to hijack this board, but I could really use the combined intellect of those who did 4U maths (I just couldn't keep up when I tried in '09), about Imaginary Numbers. Now, my friend (who is American, thought that might be relevant) insists that Imaginary Numbers exist on their own plane of reality, or something similar. From what I gathered through our own research, she seems to be talking about the Complex Number System. Please, can someone enlighten me on the matter (I'm actually interesting in learning about this further, not just taking an answer for a silly argument and leaving) more?

they are the same shit - he/she is prob refering to the graphical intepretation you do at school?

Yes

Complex Plane

When you graph complex numbers, the real part is the x-axis and the imaginary is the y-axis. It's called an Argand Diagram.

They're the same thing, Imaginary numbers exist in their own plane but it's called the Argand diagram. It's a geometrical interpretation.

It's not really a plane of reality. More its a graphical interpretation of complex numbers, which is why you can't have a complex number locus.

RULE 1 of Complex Numbers: They cannot be graphed
