Dirk,
What is the square root of -1?
How about -4?
Negative numbers can't have square roots huh?
:)


Not real square roots. The consideration of the solution
of the equation x^2 + 1 = 0 led to an entire new class of
numbers, namely imaginary and complex numbers.

???
x^2 + 1 does not equal 0.

The intent of the problem is to find the value(s) of x
such that the equation is satisfied.


(0, i) and (0,-i), there being two roots.

-i * -i = (-1)*i * (-1)*i = 1 * i^2
i^2 = -1 by definition. Does Spaceman understand "definition"?

I understand the definition of imaginary.
And since I know that definition, I know
x^2+1 = 0 is still not logical no matter how much
imaginary crap you throw under it.
