Understanding Sinusoidal Functions

The video introduces sinusoidal models, focusing on the graphs of sine and cosine functions. It explains key concepts like amplitude and period, and presents the general form of sinusoidal functions. An example of modeling tides at the Bay of Fundy is used to illustrate these concepts in practice.

What is the primary focus of the video tutorial?

• Exploring sinusoidal models

• Learning about quadratic equations

• Understanding linear functions

• Studying exponential growth

How does the sine graph start?

• At (0, 0)

• At (1, 1)

• At (1, 0)

What is the maximum value of the sine function?

• 2

• 0

• 1

• -1

What is the amplitude of a sinusoidal graph?

• The distance from the maximum to the minimum

• The width of one period

• The height from the principal axis to the peak

• The distance between two consecutive peaks

What does the parameter 'b' in the general form of a sinusoidal function represent?

• The period

• The horizontal shift

• The vertical shift

• The amplitude

In the example problem, what is the amplitude of the function?

• 1.5

• 0.75

• 2.0

• 1.0

How is the period of a sinusoidal function calculated?

• The difference between two consecutive peaks

• The sum of the maximum and minimum values

• 360 divided by the parameter 'b'

• 360 divided by the amplitude

What is the significance of the principal axis in a sinusoidal graph?

• It is the starting point of the graph

• It is the line about which the graph oscillates

• It is the minimum value of the graph

• It is the maximum value of the graph

Which of the following is an example of a real-world application of sinusoidal models?

• Linear growth of a population

• Exponential decay of a substance

• Tides in the Bay of Fundy

• Constant speed of a car
