<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 $0$ to $2 \pi$ units.

From a sketch of the graph;

$0 \ to \ \pi = 1.5 \ cycles\\\\\pi \ to \ 2\pi = 1.5 \ cycles$

$Frequency =1.5 \ + \ 1.5 = 3 \ Hz$

Thus, the frequency of the sinusoidal graph is 3 Hz.
