Amplitude and Period Practice

What is the amplitude of a sine function?

Back

The amplitude of a sine function is the maximum distance from the midline to the peak (or trough) of the wave. It is always a positive value.

Front

What is the effect of changing the amplitude in a sine function?

Back

Changing the amplitude stretches or compresses the graph vertically. A larger amplitude results in taller peaks and deeper troughs.

Front

What is the effect of changing the period in a sine function?

Back

Changing the period affects the width of the graph. A smaller period results in more cycles within the same interval, making the graph appear 'squished'.
