"there are two definitions of sqrt. The one that you are using is that
'sqrt(x) is the positive real number y such that y^2 = x'". Well not
exactly. I was using the definition that sqrt(x) = positive real number y
such that y^2 = x when x >= 0 and sqrt(x) is a positive real number (y * %i)
such that (y*%i)^2 = x when x < 0.
It is a special case. If it causes problems then it is something I have not
thought through enough. I can't figure out what is wrong with my special
case definition. I am a total klutz. I now know what the problem is, I am
a total klutz.
I should go do homework or something else.
Sorry,
