mmmmm !

If i=sqrt(-1) then i^2=-1 so by substitution,

        1/i     = -(-1)/i

                = -i^2/i

                = -i

So 1/sqrt(-1) <> sqrt(-1) but 1/sqrt(-1) = -sqrt(-1)

Some say there is no magic but, all things begin with thought then it becomes
academic, then some poor slob works out a practical way to implement all that
theory, this is called Engineering - for most people another form of magic.
