<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.
