CNX: Definition of the Z-Transform. 2.Pi is also referred to as the circular constant Archimedes . A more accurate fraction of Pi is(104348 / 33215). This is accurate to 0.00000001056%.. A . TRAVON TODDRICK. The first person to use the Greek letter Pi was Welshman William Jones in 1706. He used it as an abbreviation for the periphery of a circle with unit diameter. Euler adopted the symbol and it quickly became a standard notation.. The Unit Circle. The Unit Circle. Has a radius of 1. Center at the origin. Defined by the equations:. a) . b) . The Unit Circle. The real number . t. corresponds to the distance around the unit circle.. P. (. n. ) be the perimeter of an . n. -. gon. inscribed in a unit . circle. . (a). . Explain. , intuitively, why . P.
