focal point parabola formula Focus of a Parabola A parabola is set of all points in a plane which are an equal distance away from a given point and given line The point is called the focus of the parabola and the line is called the directrix The focus lies on the
Focal Chord The focal chord of a parabola is the chord passing through the focus of the parabola The focal chord cuts the parabola at two distinct points Focal Distance The Definition A parabola is a curve where any point is at an equal distance from a fixed point the focus and a fixed straight line the directrix On Paper Get a piece of paper draw a straight line on it then make a big dot for the focus not

The formula for finding a parabola s focus is y x 2 a 4 This equation takes into account both the vertex and directrix where a represents either value Knowing these values allows you to Definition and Properties of a Parabola A parabola is a plane curve every point of which has the property that the distance to a fixed point called the focus of the parabola is equal to the
The focal parameter i e the distance between the directrix and focus is therefore given by p 2a where a is the distance from the vertex to the directrix or focus The surface of revolution obtained by rotating a parabola A parabola is the set of all points which are equidistant from a point called the focus and a line called the directrix Later on we ll show that this leads directly to the usual
