This is your homework to calculate the ratio between circumference and diameter of any circular object nearby you...... then I show you magic .. your answer is nearly equal to 3.141...
Pi is an irrational number. This is equal to the ratio between the circumstance and diameter of the circle. It is generally symbolized by a greek symbol "π". It is also known as Archimedes' constant.
There is no final digit of pi, no end of pi. Its value is lies between 3 and 4. 3 is an odd and 4 is even. So pi is neither odd nor even. It is simply a constant which has a huge function in physics, chemistry and Mathematics. It is nearly equal to 3.14259.
The history of pi is belonging to India as per some data on the internet. The secret is behind a shloka of Aryabhatta
"chaturadhikaM shatamaShTaguNaM dvAShaShTistathA sahasrANAm AyutadvayaviShkambhasyAsanno vr^ttapariNahaH."
It means calculate 4+5+6+7+....+100 and multiply by 8 and added to 62000 the result is nearly equal to the circumference of a circle having radius 20,000.
This is the reason why it is claimed that the discovery of pi is in India by Aryabhatta (4700 years ago). Then the symbol gets popular in 1737 by Leonhard Euler. Euler gives some mathematical expression related to π. These equations are:
e iπ + 1 = 0. Where e is Euler's number i is an imaginary number π is the ratio between circumference to its diameter.e ^ix = cos x + i sin x .
Pi day is celebrated on the 14th march of every
Year as this date represented as 3.14, which is
equal to the value of pi.
