Ah just a friendly reminder that all those geometry, calculus and algebra classes in high school have been completely useless in real life. I was too stupid for trig but then again so was 97% of the student population as well.
Shailynn - not useless at all. That was a funny joke that would be lost on you if you didn't at least learn something!
I once had a math teacher who admitted most of us don't use any advanced math in life, but he said he thought the discipline of leaning math was good for growing minds and brains. That comment has stuck with me...I think we're all better off having had to at least go through algebra.
But the joke is correct. j or root of -1, is use to represent imaginary power VARs (volt amps reactive). Real power is watts. Toasters, light bulbs, electric stoves use watts. Motors require reactive power (VARs).
Here's one even more esoteric for those of you who know some advanced calculus (thought it doesn't have to do with strippers) A plane was flying from Warsaw to New York and it encountered turbulence. The pilot went on the intercom and asked everyone to move to the left side of the plane. Why? asked the co-pilot. The pilot answered, Everyone knows that poles in the right half-plane are unstable.
hoarker, i, also known as the square root of -1, is called an imaginary number because it isn't a "real" number, not because it doesn't exist. And yes, the equation x*x = -1 has 2 solutions, i and -i.
These ideas have little meaning in normal conversation. Negative numbers have to do with points of origin and replaced by concepts like left, right; up, down, etc. Imaginary numbers are mostly significant for understanding wave forms.

High school math just kicked in.

Wrong. For mathematicians the square root of -1 = i
In electrical engineering the root of -1 is j

A couple of high school math jokes:

A farmer counted 196 cows in the field.
But when he rounded them up, he had 200.
