High School Musical

If you’ve watched Disney’s High School Musical, you might remember a scene where the female lead corrected the teacher “shouldn’t the second equation read sixteen over pi?”
What was written on the board looked vaguely familiar, and so it got me trawling over the world wide web looking for details to no avail. I later found out from one of the world’s renown expert on 
that indeed the equation is one of three series that appeared in Ramanujan’s work “Modular equations and approximations to 
” Naturally, I went back to the web and this time hit the jackpot. Two screencaps:
Ramanujan’s series
Now if you want to watch the video, here’s the link.
It happens in the first minute. So you don’t have to wait too long.

There’s a great article in a recent Scientific American by Jonathan Borwein and Peter Borwein on “Ramanujan and Pi.” The series is written in different form, as
. Each new term betters 
by about eight digits. This development in 1914 was a HUGE improvement over Gergory’s (1671) arctangent-of-1-equals-pi-over-four series expansion, convergence to a any reasonable approximation requiring hundres of terms. Machin’s (1706) arctangent expansion was better, but nothing like Ramanujan’s.
