Conic Section | intersection of a plane with one or both nappes of a double cone. |
Circle | The locus points of points in a plane that are equidistant from one point, called the center |
Ellipse | The locus of points in a plane such that the sum of the distances from any point in the locus to two points, called the foci, is a constant |
Hyperbola | The locus of points in a plane such hat the difference of the two fixed points called the foci is a constant |
Parabola | The locus of points in a plane that are equidistant from a line and a point not on the line |
Major Axis | The line through the vertices of an ellipse |
Transverse axis | the line joining the two vertices of an ellipse |
Directrix | the line along with a point not on the line which is used to generate a parabola |
Eccentricity | a Measure of how close an ellipse is to being circular |
Astmptote | one of two lines through the center of a hyperbola that the hyperbola approaches but never intersects |
Focus | one of two points such that the difference of the distances from any point on the hyperbola to the foci is a constant |
