...sometimes I am glad that I decided it was more important to be funny than it was to be smart.

Fiz > FWIW, it would probably be helpful if you have at least a little idea what a "Complex number" is


Ahhhhh . . .
The square root of negative one. Usually written as '1 + i' or '5 + 7i' or even such strange things as '2.379 - 4.73i'

I STILL remember being told early in my Mathematics education "You can NOT take the square root of a negative number!" . . . And then learning that when one takes the square root - it should be 'Plus or Minus' the square root. And, finally, Imaginary Numbers.

And Vectors. Vectors and imaginary number arithmetic go hand in hand.

Interesting thing about Python (Programming) . . It seems to like complex numbers. I wrote some code to implement the quadratic equation . . and it gave me the answer - complex numbers and all.
