Pi can be expressed as an infinite power series.

Pi = 4 x summation n from 1 to infinity ((-1)^n+1)/(2n -1)

As n gets large, you would end up adding and taking away very small amounts to the summation, and this goes on forever, so this shows that Pi is irrational.

You can also use the trig function Sin to estimate Pi.

n x Sin (180 / n) gives a good estimate to Pi when n is large.

To compute m additional digits of Pi by hand, using the above power series or any other method, would be laborious. Using a computer package like Maple would make the job easier.

22/7 is NOT pi, it is just an approximation. Divide the circumference of a circle by its diameter and you get pi. The more accurate the two measurements, the nearer you will get to pi.

This is a fantastic Question!!

OK we can start this question in one of two ways, firstly let us look at the formula for calculating the circumference of a circe

C=Pi*d (c=circumference, Pi = Pi , D = diameter

a bit of algebra means we can get to

pi=C/D

Now if we can produce a circle for wich we know two values C and D we can work out pi. Take a look at these links they explain much better than Me

They have very good memory. Because there is no easy algorithm for calculating the digits of pi in your head.
