What are the "best" values for length of needle $(l)$ and distance between paralles $(d)$ for an accurate approximation of $\pi$? Does it have to be $l=d=1.0$ or $l or $l>d$? Thank you

    Your question isn't very clear. Care to elaborate a little? What to intend to say by $l-d-1.0$ exactly?2012-04-04

    example: which is the best conmbination for the most accurate approximation of Pi? 1. d = ℓ=1 2. d=1, ℓ=0.8 3. d=1, ℓ=0.6 4. d=1.2, ℓ=1.02012-04-04

    Lazzarini's experiment is where we want to derive $335/113$ by giving $l$ and $d$ a good ratio, then we continue the experiment until we have reached $335/113$ as the exact ratio.2012-08-16
