Cookie, explain how you can have the square root of minus 1?!? I mean, I thought/think that the square root is like the opposite of ^2, as + is opposite to -. Since x^2 = x*x, the answer is always positive ( -3 * -3 = 9 and 3 * 3 = 9). So you can't have [something]^2 and then get -1, so you can't do sqrt(-1) either. That's what I learned anyway..
