Yes, I know that in 1882 Lindemann proved that π (3.141) is transcendental, but nobody has ever proved that π = 3.141. The way the value is currenlty calculated is by using a method of integration, and as you can see here, I believe at best it is a very close approximation.


Therefore, this site is dedicated to the search for a mathematical proof using any method not based on integration.

The search for symmetry


Because the circle and the square are both symmetrical, we would expect pi/the 'squared circle' to have perfect symmetry.


Below we can see the symmetry of the tangents to the arc.





Below we can see the symmetry of the quarter squared circle.




By combining two quarter squared circles, we get the following ten formations.




The images below show the five fold symmetry of the squared circle.
