But why does e^(pi*i)=-1?  I think we understand that.  At least some of us do.  But not the 3_4_5 thing and all the rest.  It's a mystery.  It requires belief not proof.  It's philosophical.  It can't be explained.  There's no reason for that pattern to be there.  You have to admit at least that it's interesting.



First time seeing it for me! Very funny!

Why does e^pi-pi = 19.9990999...? Can someone explain the math behind that to me? Maybe there is no math. Philosophy?

Is it a Coincidence that it is so close to 20?  It's only 1/10,000 away.  But 6 9's?  Hmmm  Wait for it.
If you fall... I'll be there for you!

exp(pi)-pi=pi+pi^2/2+pi^3/3!+pi^4/4!....-pi

I don't know where that leads except for numerical result.

You've missed a term.
exp(pi)-pi=1+pi+pi^2/2+pi^3/3!+pi^4/4!....-pi
