I was thinking about how to approximate pi accurately and came up with something and all the calculations i did seem to show that its true and im wondering if its used often for calculating pi or if there is something better?(adsbygoogle = window.adsbygoogle || []).push({});

radius of this circle equals 1 and therefore calcualting a quarter area of a circle and multiplying by 4 we should get pi.

\pi=area

4(\int_0^1 \sqrt{1-x^2} dx) \approx \pi

[/tex]
