### fun with maths

just some stuff to find out what is wrong, not that hard:

Code: Select all
`         1=sqrt(1)           =sqrt((-1)*(-1))           =sqrt(-1)*sqrt(-1)           =i*i           =i²           =-1`

Code: Select all
`a=ba^2=ab2a^2=a^2+ab2a^2-2ab=a^2-ab2a(a-b)=a(a-b)2a=a2=1`

First one:
i^2 = (-1)^2 = -1 * -1 = 1

Second one:
a=b so (a-b) = 0. You can't divide by 0.

### Re: fun with maths

you're wrong on the first one, i is a complex operator, defined as the squareroot of -1, so i²=-1

Ah yeah, I shouldn't post things when I can barely keep my eyes open. The issue is that you can't split the sqrt((-1)*(-1)).
Doesn't hold for negative numbers to split it into two sqrts.
