As popular as i figured this would be, search didn't find anything!
I found this online on how to find n digits of pi
Pi = SUMk=0 to infinity 16-k [ 4/(8k+1) - 2/(8k+4) - 1/(8k+5) - 1/(8k+6) ]
I thought I knew how to use it until i tested it out manually on my calculator and got some funky answer. Has anyone seen this before? How is it used? (heh i thought i knew :p )
:)
I was at my dad's house (no internet :eek: ) and I needed to find pie to a few more digits then I knew..
I just put 2 points, using arcsin to find them. Whenever teh angle went above X, I knew I had gone too far, backed up one, went to next digit, etc... I got it correct up to about 12 digits... then it went beyond the capabilites of QBasic lol (It started doing it in scientific notation, which didn't give more info.
Easiest way to get Pi is 4*arctan1 (in radians btw)
i'll invent my own pi algorithms. we know that sinpi/6=1/2
so pi=6*arcsin(1/2) in radians of course :D :D :D :D
also you can get a random set of numbers, the chances of pairs being relatively prime is 6/pi^2
