The frequency of the periodic function is given by: 0.0796.
<h3>What are the period and the frequency of a function?</h3>
- The period of a function is given by the <u>distance between it's repetitions</u>.
- The frequency of a function is found <u>dividing one by the period</u>.
From the graph, we have that the period is of 4pi hours, hence the frequency is:
f = 1/4pi = 0.0796.
