Gauss called Imaginary Numbers "Lateral Numbers, " because he thought of them as existing "along with" Real Numbers.

Thanx ! Really knocked off some of my "rust"!😂

It's not usual for it to be j, i is the typical notation for sqrt(-1). Good to know the options though.

I don't get it. Why is 1024 a COMPLEX number but -44.1 a REAL number?

Please Sir, I want to know
?Is there any difference between mapping and function

Not bad but i would stick with i not j, as j, k, l is used in hypercomplex numbers when using complex numbers in higher dimensions.

So... You basically introduced i with a different variable and then went on and explained how a cartesian coordinate system can be converted to polar and the quickly wrote down this 'eulers formula'. I don't get how that is of any use when calculating imaginary numbers...
