When the plane figure is tilted and cut only one cone to form a bounded curve, then it generates a/an _______________.
Ellipse
How can you determine the orientation of an ellipse?
By comparing the denominators of the two fractions
What is the orientation of an ellipse if the higher denominator is on x^2?
horizontal
What would be your basis if the orientation of an ellipse is vertical?
The higher denominator is on y^2.
This is the middle inner most part of an ellipse.
center
We denote a co-vertex as __________.
W
What is the singular form of foci?
focus
What is the plural form of vertex?
vertices
What is the center of an ellipse if the vertex is at (h,k), and the orientation is horizontal?
C: (h,k)
Name one standard form of an equation of a parabola.
x^2 = 4py, x^2 = - 4py, y^2 = 4px, or y^2 = - 4px
It is the sharpest turning point of a parabola.
Vertex
True or False. Directrix is a line parallel to axis of symmetry.
False, parallel.
How can you determine the opening of a parabola?
By looking at the same format as the given equation in the table.
What is the equation of axis of symmetry when a parabola opens to the right, and the vertex is at (h,k)?
x = h - p
