What is the frequency of the sinusoidal graph?

Alright, lets get started.

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 repates 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

Hope it will help :)

but which class are u may know that first
