Pi is the number you get when you divide a circle's circumference by its diameter. The first digits, 3.14, are well known but the number is infinitely long. Extending the known sequence of digits ...
Additionally, PI broke down from the ascending support trend line for an instant in September (black circle). However, it immediately bounced, reclaiming the trend line shortly afterward.
Archimedes determined the upper and lower range of pi by finding the perimeters of ... ever closer in length to the circumference of the circle and thereby come up with his approximation.
