PI stands for polarization index. We need to find IR value(IR1) for 1min and again find the IR value(IR2) for 10min. PI=IR2/IR1
In 499ce, he is in 23rd years old .he will find out the approximation of pi
There is no recorded single discoverer of the value of pi. Although, it has been recorded that the Egyptians were aware of pi.
You cannot find the "PI" of anything Pi is a set numerical value, PI = 3.14159265358979323846… (It goes on forever) But in geometry we consider Pi to equal 3.14
Pi is irrational and goes infinitely, so there are always new digits to be calculated. No scientist is trying to find the value of PI. They know it. Pi is 4 times the arc-tangent of 1 OR Pi = 4 x atan(1). The exact digits go forever but that doesn't mean they change. The digits of the value of pi will always be the same, it just can't be written completely or exactly in normal decimal number notation. For mere mortals, like you and me, it's just as good to say 'three and a little bit'!
The first to find the value in pi were the Babylonians and Egyptians.

If you mean the value of pi then its value is of a circle's circumference divided by its diameter and pi is an irrational number that can't be expressed as a fraction.
