Amplitude and Period

Today in class we talked about amplitude and period.

How would you define amplitude?
How would you define period?

Can you identify the amplitude and period from the graph below? (Note π is 180° and 2π is 360°) Eventhough we haven't studied this specific graph, can you create an equation using sine that will give you this graph?

Can you determine the amplitude and period just by looking at the equation? For instance, in the equation y = 12 sin (4x), what is the amplitude? What is the period?
