Pi se yon lèt grèk ki deziyen yon nomb.
Senbòl li se
[[

Liy 15 :
Nou konnen kèk chif sou li : 3.14159265358
[[Matematisyen]] [[endyen]] sa [[Srinivasa Ramanujan]] te fè anpil travay sou li, li bay fòmil pou kalkile valè li yo ak yon òdinatè :
<br />
<math> \frac{1}{\pi} = \frac{2\sqrt{2}}{9801} \sum^\infty_{k=0} \frac{(4k)!(1103+26390k)}{(k!)^4 396^{4k}} </math>
Ak fomil sa, li pèmèt jenere dot fomil pli jeneral :<br /><br />
<math> \frac{1}{\pi} = 12 \sum^\infty_{k=0} \frac{(-1)^k (6k)! (13591409 + 545140134k)}{(3k)!(k!)^3 640320^{3k + 3/2}} </math>
<br />
