Correct. This is an assumption made about imaginary numbers. If we assume there's a number i which when multiplied together gies a negative number: i x i = -1. Given this assumption, i = sqrt(-1)
But you have to know i is this "imaginary number", or else i could be anything and the relationship i^2 = -1 could be incorrect.
Correct. This is an assumption made about imaginary numbers. If we assume there's a number *i* which when multiplied together gies a negative number: `i x i = -1`. Given this assumption, `i = sqrt(-1)`

Yes. Thats why typically lower case i shouldnt be used as a variable to avoid confusion. ME major here. Did 3 calc classes, diff eq., and numerical methods.

Right, which gets back to my point about "Nope, imaginary numbers. I'm out."
Too many axioms for me to handle. Plus, I've never found a practical use for imaginary numbers because I'm not an electrical engineer.
