Calculate the z score
This is calculated as:
So:
The frequency of the sinusoidal graph is 3 Hz.
<h3>What is frequency of sinusoidal graph?</h3>
The frequency of a sinusoidal graph is the number of complete waves for every 2π units.
The frequency of the sinusoidal graph is determined by counting the number of complete waves from to
units.
From a sketch of the graph;
Thus, the frequency of the sinusoidal graph is 3 Hz.
