Question

I need help with this question. I just don’t understand it.

Answer 1

The frequency of the sinusoidal wave is,
`(2)/(\pi)`

Explanation:

The frequency of a sine wave function states that the number of cycle it will completes in every second.

The formula for frequency:

`frequency = (1)/(Time period)`

From the given graph:

Time period =
`(\pi)/(2)`

then;

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

Therefore, the frequency of the sinusoidal wave is,
`(2)/(\pi)`
