    Concept A parabola is the curve formed from all points that are equidistant from the directrix and the focus. The parabola focus is a point from which distances are measured in forming a conic and where these distances converge. A parabola directrix is a line from which distances are measured in forming a conic. The line perpendicular to the directrix and passing through the focus is called. Focus and directrix The ellipse and the hyperbola are often defined using two points, each of which is called a combined distances from these foci is used to create an equation of the ellipse and hyperbola. A parabola has one focus point. The graph wraps around this focus. The equation of a parabola can be created using a combination of distances from the focus and from a line.

Directrix 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 directrix is perpendicular to the axis of symmetry of a parabola and does not touch the parabola.

If the axis of symmetry of a parabola is vertical, the directrix is a horizontal line. Directrix is a spaceship in the Lensman series of novels by E. Smith.

INC. book, one can define a conic section purely DIRECTRIX terms of plane geometry: it is the locus of all points P whose distance to a fixed point F (called the focus) is a constant multiple (called the eccentricity e) of the distance from P to a fixed line L (called the directrix).For 0 1 a hyperbola.

directrix (plural directrixes or directrices) A female who directs ; a directress. (geometry) A line used to define a curve or surface ; especially a line, DIRECTRIX distance from which a point on a conic has a constant ratio to that from the focus.

directrix[də′rektriks] (mathematics) A fixed line used in one method of defining a conic; the distance from this line divided by the distance from a fixed point (called the focus) is the same for all points on the conic.

A curve through which a line generating a given ruled surface always passes. Directrix in artillery, a specially equipped sector. Directrix definition is - directress. 2: a fixed curve with which a generatrix maintains a given relationship in generating a geometric figure specifically: a straight line the distance to which from any point of a conic section is in fixed ratio to the distance from the same point to a focus.

In this series we will explore parabolas for conic sections. We will explore parabolas that not only open vertically but horizontally. We will learn a new equation to write that will help use determine the parts of a parabola as explore throughout the conic sections unit.

Directrix of a Parabola. A line perpendicular to the axis of symmetry used in the definition of a parabola.A parabola is defined as follows: For a given point, called the focus, and a given line not through the focus, called the directrix, a parabola is the locus of points such that the distance to the focus equals the distance to the directrix.

Define directrixes. directrixes synonyms, directrixes pronunciation, directrixes translation, English dictionary definition of directrixes. directrixes or directrices 1. directrix x 5. The directrix is above / below / left of / right of the vertex.

This is a vertical / horizontal parabola. The equation for the directrix is x 5 2c, so c 5 5. 2 Circle the general form of the parabola. y 5 1 x2 x 5 1 y2 4c 4c Substitute the value of. The first thing we have to do when looking for the focus and directrix is to find the vertex of our parabola and we have two different ways of doing that.

We have to get y equals first and foremost and we could either complete the square, or we can just do -b over 2a to find the x. Get an answer for '`y=-7` Write the standard form of the equation of the parabola with the given directrix and vertex at (0,0)' and find homework help for other Math questions at eNotes.

Your source book on the directrix is good, and is a bit more specific than what I had found. A neat book for the history of this marker is "Forest Park" by Caroline Loughlin and Catherine Anderson, It is partially online (snippets) but can be found in.

Question parabola with vertex at (0,0) and directrix at x=-3 Answer by lwsshak3() (Show Source): You can put this solution on YOUR website. A line perpendicular to the axis of symmetry used in the definition of a parabola.

A parabola is defined as follows: For a given point, called the focus, and a given line not through the focus, called the directrix, a parabola is the locus of points such that the distance to the focus equals the distance to the directrix.

Hi Seth — Since our directrix is vertical, we know the parabola opens either to the left or right. Because the directrix is x=-3, and the focus is at (-2,1), we know the focus of the parabola is to the right of the directrix. Thus, the parabola opens to the right. Next, find the point on the directrix that has same y-coordinate as the focus.

Definition of Ellipse Ellipse is the locus of point that moves such that the sum of its distances from two fixed points called the foci is constant.

The constant sum is the length of the major axis, 2a. Define directrix. directrix synonyms, directrix pronunciation, directrix translation, English dictionary definition of directrix. n. pl. directrixes or directrices 1.The directrix represents the energy of a parabolic trajectory.

If you throw a ball, then (ignoring air resistance) it will have a parabolic trajectory. The directrix of this parabola is a horizontal line, the set of all points at a certain height in the parabola's plane.

This height is the energy in the ball. A parabola is the set of all points in the plane equidistant from a given line called the directrix and a given point not on the line, called the focus.

For a right opening parabola having equation, y^2 = 4ax, The equation of diretrix is y = -a and the co ordinate of the focus is (a, 0).
