How to find the vertices, foci and center of an ellipse

The video tutorial explains how to find the standard form of an ellipse and determine its properties, such as the center, vertices, foci, and eccentricity. The instructor uses a step-by-step approach to complete the square, identify the major axis, and calculate the necessary values. The eccentricity is discussed in terms of its impact on the shape of the ellipse, whether it appears more circular or elongated.

What determines the orientation of the major axis in the standard form of an ellipse?

• The value of 'b' in the equation

• The larger number under the variable

• The position of the center

• The value of 'c' in the equation

How do you find the center of an ellipse from its equation?

• By taking the opposite of h and k

• By identifying the coefficients of x and y

• By calculating the midpoint of the vertices

• By using the distance formula

If a^2 = 100, what is the value of 'a'?

• 50

• 20

• 10

• 5

What is the relationship used to find the foci of an ellipse?

• c^2 = b^2 - a^2

• c^2 = a^2 * b^2

• c^2 = a^2 - b^2

• c^2 = a^2 + b^2

How can you simplify the square root of 80?

• 4√5

• 2√20

• 16√5

• 8√5

What does the eccentricity of an ellipse indicate?

• The position of the center

• How circular or elongated the ellipse is

• The distance between the foci

• The size of the ellipse

How is eccentricity calculated for an ellipse?

• c/a

• a/c

• a/b

• b/a
