What is the amplitude of a sine function and how does it affect the graph?

Back

The amplitude of a sine function is the maximum distance from the midline to the peak (or trough) of the graph. It affects the height of the peaks and the depth of the troughs.

What is the midline of a sine function?

Back

The midline is the horizontal line that runs through the middle of the graph, representing the average value of the function.

How does changing the amplitude affect the graph of a sine function?

Back

Increasing the amplitude stretches the graph vertically, making the peaks higher and the troughs lower. Decreasing the amplitude compresses the graph.
