The anti-derivative of any constant c, is just c*x. Thus, the antiderivative of pi is pi*x. We can verify this by taking the derivative of pi*x, which gives us pi.

Most pies are circular. Okay, that was a cheap joke. The actual answer is that pi is the ratio of the diameter of a circle to its circumference. That means it shows up a lot… in equations involving circles and circular things. It also shows up in a lot of places you might not initially expect. For example, the sum of the infinite series 4 - 4/3 + 4/5 - 4/7 +4/9 ... is Pi. (MORE)

Pi Day is celebrating the mathematical constant π (pi). It is officially observed on March 14, 3/14 being the first three digits of the numerical value pi. It can also be cel…ebrated on March 4 - when 14% of the month of March has passed. Pi Approximation Day on the other hand is another math holiday observed on July 22, due to π being about equal to 22/7. (MORE)

Pi is a number. You get pi when you divide the circumference of a circle by it's radius. 22/7=3.14 is the closest fraction.

The early history of N (pi) from textual sources roughly parallels the development of mathematics as a whole. Early evidence points toward use of an approximation for the len…gth of 'circumference' with respect to its 'radius' (~ 3 1/7) in the designs of the pyramids in Egypt. The Great Pyramid (2500 BC) was built with a perimeter of 1760 royal cubits (1 royal cubit ~ 20.64 inches or 525 mm) and a height of 280 cubits; the ratio 1760/280 ~ 2π ~ 6.29. (N ~ 3.14) Pi was discovered by the Greeks by a process called exhaustion. They observed that any polygon could be divided into triangles whose areas could be combined to get the area of the shape, so they tried the same thing with circles. They then factored in the radius of the circle, and they found pi. These triangles can theoretically get infinitely smaller, which is why pi is an irrational number. (MORE)
