pi ( ) Telecom Definition

The sixteenth letter of the Greek alphabet, is used to mathematically represent the ratio of the circumference of a circle to its diameter, which is equal to 3.14159265358979323846. . . . Pi is an infinite decimal, at least as far as we know. Pi has been calculated to many millions of decimal places, but to no end. Further, no repeating pattern has ever been discovered, and many mathematicians maintain that a repeating pattern is impossible. Pi has many important mathematical uses. For example, the area of a circle is pi times the square of the length of the radius, or A = r 2 , or pi r squared. Everyone, from middle school, knows that to be impossible, of course -- pies are round, some cakes are squared.
