Euler phi-function
Author: Marian Olejar, Jr. Created: Dec/06/2006 Last edit: Dec/06/2006
complex analysis:
The Euler `phi`-function can be defined as the degree of the nth cyclotomic polynomial: `phi(n)` = deg`(Phi^n(x))`. If n`>=`1 is an integer, then `phi(n)` is the number of integers k with 1 `<=` k `<=` n and (k, n) = 1.
