Chapter 8.7, Problem 8E

Interpretation Introduction

Interpretation:

Whether the system necessarily has a $\text{T}$-periodic function is to be checked and if not, an $\text{F}$ should be found which provides a counterexample.

Concept Introduction:

A function is said to be the periodic function if this satisfied the condition,

$\text{f}\left(\text{x}\right)\text{ = f}\left(\text{x + nt}\right)$

Where, $\text{t}$ is the period and $\text{n=1, 2…}\text{.}$
