e^(pi*i)
« on: January 02, 2006, 06:43:00 pm »
Ok, so calcul831415 has e^(pi*i)=-1, and he doesn't know why.  While doing math hw, I stumbled upon Euler's Forumula, which states that e^(x*i) = cos(x)+sin(x)*i.  Therefore, cos(pi) = -1, sin(pi) = 0 *i = 0, 0+-1=-1.  There you have it.

That must be the inverse of ln(-54125+1)=imaginary pi.
It would be cool if pi was a repeating decimal, but it would have about 1000000 digits in each cycle. :)smile.gif
