In next 20 minutes your thinking about π (Pi) is going to change .

Explore the hidden side of π .Yes it is not the History but the future of Pi you are going to explore. The most used mathematical constant which remained a secret for thousands of years will be unfolded. know what is common between square , triangle and circle? find yourself how circle is not a special shape but only a regular polygon with infinite sides Don't you want to know a single formula , which you can use for calculating the area of square, triangle and the circle? .Calculate yourself the accurate value of π up to any digits, that too in seconds .You will also know the interesting relation between accuracy of pi and its result on circumference of circle! So let us start the journey where no one has gone before.

Chap-1 is about Pi day, starting point of the journey.

Chap-2 is the brief history of origin and works done on Pi. About the people involved in search of accuracy of Pi.

Chap-3 will ignite a question about peculiarity of the constant Pi .

Chap-4 will show different probable paths for solutions to the above question.

Chap-6,7,8,9 will successfully explore new constants equivalent to Pi in shapes such as square, triangle and hexagons.

Chap-10 will find a general formula about finding Pi equivalents for each shape.

Chap-11 will establish a bridge between all new pi equivalents to the Pi.

Chap 12 is about how much accuracy of Pi is enough for the world.

Chap 13 end of journey with a great feeling about all the new friends of PI.
