Question

how to find the periodicity
​

Answer 1

Step-by-step explanation:

In order to determine periodicity and period of a function, we can follow the algorithm as :

Put f(x+T) = f(x).

If there exists a positive number “T” satisfying equation in “1” and it is independent of “x”, then f(x) is periodic. ...

The least value of “T” is the period of the periodic function.
