What is the amplitude of this graph?

Remember: Amplitude is the distance from the midline to the maximum.

Answer explanation

If the midline of sin(x) is at y=0 and the maximum of sin(x) is at 1, the distance from the midline to the maximum is 1.

What is the period of this graph?

Remember: Period is one full revolution of the graph.

• 1

Answer explanation

From 0, the graph of sin(x) completes one full cycle at 2pi. This is where it begins to repeat itself.
