Question

What is the frequency of the sinusoidal graph?

Answer 1

I believe it would be pi over 2 because frequency is the distance between either two of the high points or the low points, if i remember correctly.

Answer 2

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
`(\pi)/(2)` time, it repeats its pattern.

Hence the period of the graph is
`(\pi)/(2)`.

Now we need to find its frequency.

The formula for frequency is :

`frequency = (1)/(period)`

`frequency = (1)/((\pi)/(2))`

`frequency = (2)/(\pi)`

This is the answer:
