If S(n) = 1 + 1/2^2 + ... + 1/n^2 then lim(S(n), n -> oo) = Pi^2/6 =
zeta(2). (Riemann's zeta function.) The proof(s) that zeta(2) = Pi^2/6
are non-trivial and, as far as I know (which isn't _very_ far), not
So, it _is_ true that 1/2^2 + ... + 1/n^2 < Pi^2/6 - 1 < 1. Proving
that fact, independent of knowing zeta(2), will require some cleverness
