Periodic Functions

A Periodic Function is a function where the entire graph is formed from copies of a particular portion at specified intervals.

The Function :$ f(x) = sin(x)\,\! $ is a periodic function with a Period :$ T = 2*\pi\,\! $.

This sine wave function repeats itself every period of :$ 2*\pi,\! $

Periodic function $ f(x) = sin(x) $. The graph consists of copies of the values $ T = 0 $ to $ T = 2*\pi $.

Non-Periodic Functions

The Function :$ f(x) = cos(e^x)\,\! $ is non-periodic since the graph does not consist of copies of one part of the graph positioned one after the other.

Non-Periodic function $ f(x) = cos(e^x) $. The graph has no visible repeated copies of one part of the graph.
