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 agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.
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?
