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.

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.

Front

What is the effect of a negative coefficient in front of a cosine function?

Back

A negative coefficient reflects the graph across the midline, flipping it upside down.

What does the term 'phase shift' mean in trigonometric functions?

Back

Phase shift refers to the horizontal shift left or right for periodic functions, affecting where the cycle starts.
