| I stumbled across this on wikipedia, and can't figure out how it works because it's beyond what I've experienced in maths (I'm only in year 11) e^(pi*i)=-1 What? How do two irrational numbers and a non-real number become a rational, real number? oh, and use google calculator if you want proof. I tried to link but it didn't work

| Bah what kind of silly question is that everyone know that e^(pi*i) + 1 = 0 its called Euler's identity ok e^(i*x) = cos x + i*sin x
e^(i *pi) = cos pi + i*sin pi.
since
cos pi = -1
and
sin pi = 0 e^(i *pi) = -1
e^(i \pi) +1 = 0 There we go, now for the source because I had never seen that equation before http://en.wikipedia.org/wiki/Euler%27s_identity I was pretty damn amazed as well, did you see it in this article? anyways I think I might do some homework because that's what I'm meant to be doing :P

| Ahh, thankyou. I had another look at the article (looked over it before) and it makes a tad more sense now  I guess this is what happens when I only have just over a year 10 math education. I'll probably slap myself in two years time and say "YOU IDIOT!"
