The not-to-scale graph is inserted, thanks to the Socratic graphic utility.

#### Explanation:

The amplitude is 2. A little extra 2+ is used to avoid small gaps at

crests and nadirs.

The period of sin kt is

So, for two cycles the x-span should be

So, choose the interval

Note the ratio amplitude/period = 256. So, the need for zooming x is

understandable.
