What is the equation for pi? We tried 22 divided by 7 but it came up recurring we got 3.142857142857142857 see how it reoccurs by 142857......... can you please help us?


Replies:
One easy equation for pi is:
pi = 4(1 - 1/3 + 1/5 - 1/7 + 1/9 - 1/11 . . . )

It will take several thousand terms to begin converging.
