My favorite pi approximation is sqrt 2 + sqrt 3. This value arises in the derivation of the count of canonical sequences of length n for the Rubik's cube. On Oct 14, 2012 9:06 AM, "David Wilson" <davidwwilson@comcast.net> wrote:
I did find a possible motivation for Ramanujan's approximation to pi. It would follow from the obvious rational approximation to
zeta(4) = 1.08232323+

A much more interesting approximation is Ramanujan's π = (2143/22)^(1/4), good to 9 places.
