Transforms And Partial Differential Equations: UNIT II: Fourier Series

Definition

A function f (x) is said to be periodic, if and only if f (x +p) = f (x) is true for some value of p and every value of x.

§ PERIODIC FUNCTION:

Definition: Periodic Function

A function f (x) is said to be periodic, if and only if f (x +p) = f (x) is true for some value of p and every value of x. The smallest value of p for which this equation is true for every value of x will be called the period of the function f(x).
