How exactly would you put this into a calculator (ex. A Ti-83+)??

I hope your kidding, but just in case hit e,then ^,then (, then pi symbol, then 2nd i, then ), then enter. This also could be done easier by using the e^ symbol.

Actually, just use the e^x button.. That puts e^( in all at once and saves space to boot!

oh blah that's what i get for clicking reply before i read the whole post

Doh! the instant I read it I knew the answer was 0, but I chose 0! becuase I mistook the factorial symbol for an exlclamation point. I hope that's the reason other people are choosing 0!. I thought it was a well known fact that e to the pi i was -1!!!

i feel sorry for the poor lone idiot who voted for 1 XD

By now there's already 6 people who voted 1:

Choice__Votes__Percent
0!_______3______4.1%
1!_______1______1.4%
0_______52_____71.2%
pi_______0______0.0%
ln(i)____5______6.8%
1________2______2.7%
Huh?____10_____13.7%

At least, I think we can all agree that 3 + 1 + 2 equals 6? ;)

(Don't know how terrible that's gonna look. Copy paste it to your favorite fixed-width editor if you can't read it. The underscores are there to prevent html from killing multiple spaces.)

*yawn* Conical cross-sectional volumes and infinite series next? Some multivariable calculus maybe?

Since I'm sure that most people here just know that you can plug this into your calculator to get the answer (I won't say it, to avoid spoiling the fun for say, one person). But, the proof (and general case) is actually somewhat nifty (see the link.)

Remember: "Gauss is reported to have commented that if this formula [e^(pi*i)+1=0] was not immediately obvious, the reader would never be a first-class mathematician" (Ripped from Mathworld link above)

It would be even nicer if you provided the link.

Uh, yeah, WHAT link?

That one.

Thanks for clearing that up. ;-)

*cough* google quote *cough*

Huh?

Oops. :-D

If we were first class mathematicians, we wouldn't need calcs :)

Right...if we were first-class mathematicians, we could get supercomputer time whenever we needed it.

I voted Huh? ;)

i checked my calc for this, the answer is 0.

I didn't know the exclamation mark was the math exclamation mark. So i answered "The answer is zero!!!!!".

Yeah, I answered "huh?"
