- I don't know what method you are talking about but I have been
- thinking this problem for a long time and I found a way(the hard way)
- to find PI. I use the idea of polygon in a circle. I first use
- a square to start with. Then I turn the square into a octagon and find
- the length of the side in terms of square root of 2. And then I
- double the number of side again and again and again.....
- It works fine but the algebra is heavy. I figure square root of 2
- is easier to find than PI. A friend of mine used taylor's series
- to find Pi up to 5000 digit.
