What is the Pythagorean identity for sine and cosine?

Back

Front

Define the amplitude of a sinusoidal function.

Back

The amplitude is the maximum distance from the midline of the graph to its peak or trough.

Front

What is the period of a sinusoidal function?

Back

The period is the distance (or time) it takes for the function to complete one full cycle.

Front

What is the vertical shift in a sinusoidal function?

Back

The vertical shift is the amount by which the graph is moved up or down from the origin.

Front

Write the general form of a cosine function with amplitude, period, phase shift, and vertical shift.

Back

The amplitude is 3.

Front

How do you determine the maximum height of a Ferris wheel modeled by a sinusoidal function?

Back

The maximum height is given by the vertical shift plus the amplitude.
