Sine and Cosine Graphs

Front

What does phase shift mean?

Back

A left or right movement of the graph.

Front

Identify the function: y = sin(x) or y = cos(x)?

Back

y = cos(x)

Front

What is the equation of the graph shown?

Back

y = 1/2cos(4x)

Front

What is the period of the sine or cosine graph?

Back

2π

Front

What is the equation of the graph?

Back

y = -2 cos(x) - 3

Front

Define amplitude in the context of sine and cosine graphs.

Back

The amplitude is the maximum height of the graph from the center line.

Front

What is the range of the sine function?

Back

[-1, 1]

Front

What is the range of the cosine function?

Back

[-1, 1]

Front

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

Back

It reflects the graph across the x-axis.

Front

What does a coefficient in front of the sine or cosine function represent?

Back

It represents the amplitude of the graph.
