Identifying Conic Sections Flashcards
What is the Standard Form for the Circle?
(x-h)^2+(y-k)^2=r^2.
What is the Standard Form for the Ellipse?
Horizontal Axis: (((x-h)^2)/a^2)+((y-k)^2)/b^2=1.
Vertical Axis: (((x-h)^2)/b^2)+((y-k)^2)/a^2=1.
What is the Standard Form for the Hyperbola?
Horizontal Axis: (((x-h)^2)/a^2)-((y-k)^2)/b^2=1.
Vertical Axis: (((y-k)^2)/a^2)-((x-h)^2)/b^2=1.
What is the Standard Form for the Parabola?
Horizontal Axis: x-h=(1/4p)((y-k)^2).
Vertical Axis: y-k=(1/4p)((x-h)^2).
