How do you explain this /sci ?
>>7847898
the square root of 1 is not only 1, but also -1. so there's no contradictory in the last equality
>>7847898
you forgot the +-

You can bot fo from phase 3 to 4 while not in the Real Numbers field.
[math]\sqrt{-1}[/math] is not defined, that's the problem.

Even if it's bait, chances are that someone's going to follow the link and learn something new.
>>7847906
The typical "what are math" response.
>>7847919
no, and you know that.
don't forget to sage. This doesn't deserve to be on the first page.
thank you for your help cleaning this board.

This.
>Amerilards will disagree
>sqrt(-1)
-1*-1 = 1
-1*1 = -1 != sqrt(-1)
1*1 = 1 != sqrt(-1)
>sqrt(-1)*sqrt(-1)
>1 * 1/-1 * -1/1 * -1
It just can't be done. Fuck off.
sqrt((-1)*(-1)) != sqrt(-1)*sqrt(-1)
That's like in the first 4 weeks of calc1. With the whole math major superiority around here i'd expect this to be the answer.
something something illegal move.
sqrt(-1) times sqrt(-1) =/= sqrt((-1)(-1))
