Ellipse Properties and Formulas

The video tutorial explains how to graph an ellipse by identifying its center, vertices, and foci. It begins with an introduction to the ellipse equation, highlighting the importance of the largest denominator to determine the values of a, b, and c. The tutorial then guides viewers through finding the center of the ellipse, identifying the major and minor axes, and plotting the vertices. It concludes with instructions on plotting the foci and co-vertices, completing the graph, and summarizing the process.

What is the first step in graphing an ellipse?

• Calculating the foci

• Understanding the equation

• Finding the vertices

• Identifying the center

In the ellipse equation, what does the largest denominator represent?

• The value of 'c'

• The center

• The value of 'a'

• The value of 'b'

How do you calculate c^2 for an ellipse?

• c^2 = a^2 + b^2

• c^2 = a^2 - b^2

• c^2 = b^2 - a^2

• c^2 = a^2 * b^2

What are the coordinates of the center of the ellipse in this example?

• (3, 3)

• (2, 2)

• (1, 1)

• (0, 0)

What is the role of the center in an ellipse?

• It is the midpoint of the major axis

• It is the midpoint of the minor axis

• It is the intersection of the axes

• It is irrelevant

What is the significance of the center in an ellipse?

• It is irrelevant

• It is the intersection of the axes

• It is the midpoint of the minor axis

• It is the midpoint of the major axis

How is the major axis of an ellipse determined?

• By the sum of denominators

• By the difference of denominators

• By the largest denominator

• By the smallest denominator

If the major axis is horizontal, where is 'a' located in the equation?

• Under the x^2 term

• In the numerator

• Under the y^2 term

• In the constant term

How do you determine the orientation of the major axis?

• By the value of 'c'

• By the position of the center

• By the value of 'b'

• By the position of 'a'

How do you determine the orientation of the minor axis?

• By the position of the center

• By the value of 'a'

• By the value of 'c'

• By the position of 'b'
