What is the period of a sine or cosine function?

Back

The period is the distance along the x-axis for one complete cycle of the wave. For the standard sine and cosine functions, the period is 2π.

What is the amplitude of a sine or cosine function?

Back

The amplitude is the maximum distance from the center line (midline) to the peak (or trough) of the wave.

What is the domain of the function y=sin(x)?

Back

The domain is all real numbers, expressed as (-∞, ∞).

Front

What is the range of the function y=cos(x)?

Back

The range is [-1, 1], meaning the output values of the cosine function are between -1 and 1.

What does the term 'midline' refer to in sine and cosine graphs?

Back

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

How does a phase shift affect the graph of a sine or cosine function?

Back

A phase shift moves the graph left or right along the x-axis, altering the starting point of the wave.

What is a vertical shift in the context of sine and cosine graphs?

Back

A vertical shift moves the entire graph up or down, changing the midline of the function.

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

Back

A negative coefficient reflects the graph across the x-axis.
