| 1 = -1 1 = sqrt(1) = sqrt(-1 * -1) = sqrt(-1) * sqrt(-1) = i * i = i^2 = -1 |
this part is impossible:
sqrt(-1) * sqrt(-1)
is doesnt have an answer
you cant get the sqrt of -1, no such number multiplied by itself will get -1

sqrt(-1) is the imaginary number i. i is used to denote complex numbers and thus it is not a real number. and gotenks negative numbers dont turn positive when u sqrt them 
sqrt(-25) would be 5i where i is the imaginary number sqrt(-1)
and my calculator says undef when u try to divide by 0
sqrt(-25) would be 5i where i is the imaginary number sqrt(-1)and my calculator says undef when u try to divide by 0

I don't understand C++ I use visual basic 5.0, and it works for what i need to do.

Because
sqrt(-1 * -1) = sqrt(-1) * sqrt(-1) should actually be sqrt(-1 * -1) = -sqrt(1) * -sqrt(1) = 1
Been a while since I've done any math like this so I'm not sure it that is how it works. I hope you still remember alpha.

Aaaah.... Looking back now, I understand what alpha did.
Hehehe... *didnt know complex numbers back then*
So nooby!
But yeah, Daryl is right with the flaw.
