Periodic Function
A function f(x)is called periodic, if it is
defined for every xin the domain of fand if there is some positive number psuch that f(x+p)= f(x)The number pis called a periodof f(x).
If a periodic function fhas a smallest
period p, this is often called the fundamental periodof f(x).© 2012, Ching-Han Hsu, Ph.D.
