Front

What is the equation for the graph that represents a cosine function with a negative amplitude?

Back

Front

How do you find the reference angle for a negative angle?

Back

To find the reference angle for a negative angle, add 360 degrees (or 2π radians) until the angle is positive, then find the equivalent angle in the first rotation.

What is the formula to find the period of a sine function?

Back

Front

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 graph.

Front

What is the reference angle for 780 degrees?

Back

The reference angle for 780 degrees is 60 degrees.

Front

What does a vertical shift in a sine function do to its graph?

Back

A vertical shift moves the entire graph up or down without changing its shape.

Front

What is the effect of a horizontal shift on the graph of a sine function?

Back

A horizontal shift moves the graph left or right, affecting the starting point of the wave.
