What is a parabola? A set of all points in a plane that are the same distance from a given point called the focus and a given line called the directrix
Standard form of a parabola? y = a ( x - h ) ^ 2 + k
What is a circle? A set of all points on a plane that are equidistant from a given point called the center
Standard form of a circle? ( x - h ) ^ 2 + ( y - k ) ^ 2 = r ^ 2
What is an ellipse? Set of all points on a plain such that the sum of the distances from two fixed points is constant
Standard form of a vertical ellipse? ( x - h ) ^ 2 / b ^ 2 + ( y - k) ^ 2 / a ^ 2
Standard form of a horizontal ellipse? ( x - h ) ^ 2 / a ^ 2 + ( y - k) ^ 2 / b ^ 2
What is a hyperbola? Set of all points on a plane such that the absolute value of the difference of the distances from the foci is constant
