What is the frequency of the sinusoidal graph?

For finding frequency, we need to first find the period of the graph.

The period of a sinusoidal graph is the time interval in which it repeats its pattern.

In the graph, we can see, after time, it repeats its pattern.

Hence the period of the graph is  .

Now we need to find its frequency

The formula for frequency is

This is the answer
