Good stuff. Maybe you could mention why they were invented in the first place, also an argand diagram.
In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
Looking great! Complex numbers is one of the most fascinating topics for me.
It IS fascinating, and I don't think I have shown that so far
I intend to write more pages one day (and will include argand diagrams!) where I can hopefully show some of the neat aspects ... any suggestions?
