What is the amplitude of a trigonometric function?

Back

The amplitude is the maximum distance from the midline to the peak (or trough) of the graph. It is calculated as half the distance between the maximum and minimum values of the function.

Front

What is the midline of a trigonometric function?

Back

The midline is a horizontal line that represents the average value of the maximum and minimum values of the function. It is the line around which the function oscillates.

Front

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 vertically.

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

Back

Changing the period affects the frequency of the oscillations. A shorter period results in more cycles in a given interval, while a longer period results in fewer cycles.
