Original poster: "Loudner, Godfrey by way of Terry Fritz <twftesla-at-qwest-dot-net>" <gloudner-at-SINTE.EDU> Hi Mark Here is one answer to your mathematical question. There are many such formulas, but here is one. Pi = Arctan(x) + Arctan(y) + Arctan((x + y)/(xy - 1)) where x > 0 and xy > 1. Take x and y as real numbers, or take x and y in radian measure. In particular, take x = 1 and y = 2. Then Pi = Arctan(1) + Arctan(2) + Arctan(3). To verify the numerical example, set your hand calculator in the radian mode.
