Answer 1

`\boxed{f=(3)/(2\pi)}.`

Explanation:

Notice that the wave completes 3 oscillations at
`x=2\pi`. This means that the period is:

`T = (2\pi)/(3).`

Since the frequency is the reciprocal of the period, we get:

`f= (1)/(T) = (1)/(2\pi/3) = (3)/(2\pi).`

So the frequency is:

`\boxed{f=(3)/(2\pi)}.`
