# Proof that the squareroot of -i is 17. watch

1. squareroot of -i = (-i)^1/2 = 1 + (-i)^1/2 - 1 != 2, since 2^2 = 4 != -i.

Now 2 != 17

=> (-i)^1/2 = 17.
2. sqrt(-(sqrt(-1))) = 17???

No I don't see it.

sqrt(sqrt(-1)) = 17???

No I don't see it.
Pft, my reasoning is perfectly correct. Stop trying to mislead these vulnerable people.

2! = 2 doesn't it?
5. (Original post by ZJuwelH)
2! = 2 doesn't it?
Yes.
6. (Original post by fishpaste)
Yes.
lol.
7. (Original post by fishpaste)
Yes.
Sooo, basically the "magical proof" is incorrect. What have you been smoking tonight?
8. (Original post by fishpaste)
Yes.
And you said 2! = 17...

Flawed, sorry.
9. I never considered myself fallible.
10. (Original post by fishpaste)
Yes.
I don't understand what you've done, but I think it's pretty safe to say that it's utter crap.

Maybe I'm being stupid, but does 2! not mean 2 factorial i.e. 2*1 and therefore just 2? To be honest I lost you after squareroot (-i) =(-i)^1/2

Don't worry, happens to the best of us.

Can I get rep for that?

Just out of curiosity, where did 17 come from?

And is sqrt(-1) = 1?
14. You guys do realise that != just means "not equal to?"

Ok it's not just me being stupid, you're taking the piss. Phew! I didn't want to say anything in case I was just an idiot.

Why not use <> or ><...

17 is the magical number of the elk fairies.

No it isn't.

(-1)^(1/2) is denoted as 'i'. It doesn't exist, but is damn useful!

Programming convention uses !=
