Deanrover Posted March 21, 2008 Report Share Posted March 21, 2008 pi is 4/1 - 4/3 + 4/5 - 4/7 + 4/9 - 4/11 ............. Pretty cool hu? You should sign up for a class in Fourier Series, you would like it :( I like spectral analysis, which I believe is very very closely related.

Echognome Posted March 21, 2008 Report Share Posted March 21, 2008 pi is 4/1 - 4/3 + 4/5 - 4/7 + 4/9 - 4/11 ............. Pretty cool hu? I think e rivals you there: e^x = Sum((x^n)/n!) = 1 + x + x^2/2! + x^3/3! + ... so e = e^1 = 1 + 1 + 1/2! + 1/3! + 1/4! + ... = 1 + 1 + 1/2 + 1/6 + 1/24 + .... = 2.718281828 Quote Link to comment Share on other sites More sharing options...
skjaeran Posted March 21, 2008 Report Share Posted March 21, 2008 so e = e^1 = 1 + 1 + 1/2! + 1/3! + 1/4! + ... = 1 + 1 + 1/2 + 1/6 + 1/24 + .... = 2.718281828 Those digits are easily remembered as 2.7 Ibsen Ibsen (Henrik Ibsen was born in 1828). :( Quote Link to comment Share on other sites More sharing options...

kenberg Posted March 22, 2008 Report Share Posted March 22, 2008 No need to choose between pi and e. From Euler we have1+e^(i pi) =0 Was it Laplace who argued that the above equation proves the existence of God? Please, I mention this as an amusing aside. I sincerely hope it does not lead to pro and con arguments on this issue. Quote Link to comment Share on other sites More sharing options...
