# Math Help - Approximating pi!!!!!!!!!!

1. ## Approximating pi!!!!!!!!!!

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.

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

thanks!

2. Try arcsin. It converges faster.
