1. I'm for e myself -I just love those natural logarithms!
2. (Original post by Ben.S.)
I'm pro root pi!!!

Ben
lol rooting it doesnt make it any more irrational

No, but it's the integral of exp^(-x^2) - what fun. A beautiful piece of maths.

Another reason why I like e -it's causing me the least trouble in calculus
6. (Original post by elpaw)
i wonder if that is rational?
Infinitely unlikely.

dy/dx of e^x = e^x
nice and easy
8. What's phi? I did A-Level Maths and never heard of it!
9. dy/dx of e^x = e^x
this is the same reason i like e, and it has many uses, roots of primes i aint used all that much, and pi gets a bit boring after a while. tho phi pi and e are all cool numbers

I was wondering the same thing. Did/do you visit BBC boards?

What makes you so sure? A proof please...

phi (the 'golden ratio') = 1/2 + root5/2 and 1/2 – root5/2

I did indeed. Why, did/do you? Which ones?

Thanks for the explanation, edders.

Yeah, I used to. Can't remember what it was called now though. Your name just looked familiar.

It's the solution to the quadratic equations:
x² = x + 1, or x - 1 = 1/x.

Its all so the ratio of consecutive fibonacci numbers as they get really big, the larger divided by the smaller. apart from that its more or less completely useless.
16. Maths is a **** subject.

Maths is a **** subject.
Why?
18. (Original post by Nylex)
Why?
because it's boring, useless, and absolutely impossibly-rock-hard.
19. (Original post by Merry)
They all are good!!! but my vote is for Phi: a very interesting number!
you geek

It may be boring to you, but it's certainly not useless.
