Isn't the squaring actually multiplication by the complex conjugate when working in the complex plane? i.e., √((1 - 0 i) (1 + 0 i) + (0 - i) (0 + i)) = √(1 + - i^2^) = √(1 + 1) = √2. I could be totally off base here and could be confusing with something else...

I think you're thinking of taking the absolute value squared, |z|^2 = z z*

Considering we're trying to find lengths, shouldn't we be doing absolute value squared?
