The focus of a parabola is a fixed point on the interior of a parabola used in the formal definition of the curve.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 ...
Focus of a Parabola:In mathematics, the focus of a parabola is a point that can be used, along with a line called the directrix, to define the parabola. That is, a parabola is a set of points, such that each point on the parabola is the same distance from the focus of the ...
Vertex is a special point where the parabola has a change in its direction, thus making it the highest or the lowest point on the graph of the parabola. Focus and Directrix Distance formula is used to prove that the distance from the focus to any point in that parabola is equal to the...
3.A central point or region, such as the point at which an earthquake starts. 4.MathematicsA fixed point or one of a pair of fixed points used in constructing a curve such as an ellipse, a parabola, or a hyperbola. The American Heritage® Student Science Dictionary, Second Edition. Cop...
This is the locus of points that are equidistant from a fixed point, focus and a fixed-line, directrix. The distance between focus and vertex is mentioned by a in the equation of the parabola.Answer and Explanation: The standard equation of the parabola is {eq}(x-h)^{2} = ...
(1) The focus of a curve of degree 2—an ellipse, a hyperbola, or a parabola—is a pointFlying in the plane of the curve and possessing the property that the ratio of the distance between any point on the curve andFto the distance to the directrix is a constant equal to the eccentri...

Equation of parabola with vertex (0,0) and focus (2,0) is Ax2=x By2=2x Cy2=4x Dy2=8xSubmit If a ellipse has centre at (0,0), a focus at (-3,0) and the corresponding directrix is 3x + 25 = 0 , then it passes through the point : A(−5,−4) B(52,4) C(−...
One of the fixed points from which the distances to any point of a given curve, such as an ellipse or parabola, are connected by a linear relation. Emphasize To give emphasis to; stress She emphasized that the matter was urgent. Focus An element of a sentence that is given prominence by...
The apparatus includes select signal generating means for dividing the period of a sawtooth signal into a falling portion, a rising portion located before the central point of the positive pulse of a flyback pulse signal, and a rising portion after the central point of the positive pulse of ...
