Answer 1

The period of a sinusoidal function is the distance required for the function to complete one full cycle. In this case, observe that the peaks of the sinusoidal function occur at \(\pi\) and \(2\pi\). Therefore, the distance of the given sinusoidal can be found by calculating \(|2\pi - \pi|\)
