by writing arctan as a power series, you can obtain an approximation to arctan (1/root 3) and hence approximate pi. I've done this by multiplying my answer for arctan (1/root3) by 6 to get 3.14.... radians.(adsbygoogle = window.adsbygoogle || []).push({});

I would like to know How can this approximation be improved?

thanks!
