With out getting into complex numbers too deep it seems that when there is a square root of a negative number. ie.... sqr(-n)
That an "i" is tacked onto the value. I was reading that the starting base for an imaginary number is "i" which equals sqr(-1)
sqr(-1). So what is the actual basis for complex numbers? Are they saying that the square root of a negitive value cannot be found?
the square of a negative number is not a Real number
On the other hand Complex numbers that are so to speak two dimensional, has a real and a imaginary dimension, the square of a number will double the phase angle, reason why i^2 which has phase 90 degrees will be a real number. Euler's formula expresses this nicely:

e^i*pi=-1
