Oops I broke the laws of math.

Re: Oops I broke the laws of math.

The order of operation says to do the parentheses first, so √(-1)(-1) would have to be √(1). Correct me if I'm wrong.

Edit: Oh thanks Prime

Re: Oops I broke the laws of math.

Yeah if a is positive.

√-x * √y = √-xy

√-1 * √1 = √-1 * 1 = √-1

The expressions in parenthses are already solved, they're both -1.

Re: Oops I broke the laws of math.

√-x * √y = √-xy

√-1 * √1 = √-1 * 1 = √-1

???

yeah what's the problem with that?

Yeah if a is positive.

I just proved that a can be negative

Re: Oops I broke the laws of math.

Proof 5: 1=0

x = 1

(d/dx) x = (d/dx) 1


1 = 0

LOL this one is amazing. Where did you get this from?

You're not going anywhere, that doesn't make any sense.

Re: Oops I broke the laws of math.

√-x * √y = √-xy

√-1 * √1 = √-1 * 1 = √-1

???

√-1 * √4 = √-1 * 2 = √-4 = 2i

Just how does this not make sense?

Re: Oops I broke the laws of math.

alright 7 proofs of increasing difficulty

this should be enough to keep you bastards workin for a while

Re: Oops I broke the laws of math.

√a * √a = a

√-1 * √-1 = -1

???

You didn't proove that a can be negative.

Re: Oops I broke the laws of math.

ok ok let me articulate what a ton of you have been trying to say

√x * √y = √xy

this property only holds when neither is negative OR one of them is negative

only in the case where BOTH are negative is this illegal

Re: Oops I broke the laws of math.

Hey stargroup, you should read the first chapter of Hardy's Divergent Series book. And more if you want but the first chapter is pretty snazzy.

Proof 5 is just dumb lol...

Re: Oops I broke the laws of math.

they are all dumb. every one of them

except the sixth one which is just marginally stupid

Re: Oops I broke the laws of math.

It's just more cool when you do something that seems wrong but you get a result that's true but can't figure out why it worked (or why it should work). Or more infuriating.
