The geometric definition of a parabola is "the set of points that are equidistant from the focus and thedirectrix," which is a line that does not pass through the parabola and which is a focal length away from the vertex. Figure 1: Characteristics of a parabola. ...
Find the equation of the parabola. focus: (1,3) directrix: x=−1 Equation of The Parabola: Parabola: A parabola is a symmetric curve which is same on both the sides, that is formed when a cone is made to intersect with a plane that is parallel to the side of the cone...
The equation of the parabola is (x−h)2+(y−k)2=(ax+by+c)2a2+b2, where (h,k) is the focus of the parabola and ax+by+c=0 is the directrix. If two lines are perpendicular each other, the slopes of the lines will be m1m2=−1 ...

To find the focus, you need to know that the latus rectum is equal to "4p" when the parabola equation is written in this form: 4p(x-h) = (y-k)^2 "p" is the distance between the directrix and the vertex, as well as the distance between the vertex and ...
The fixed distance is called a directrix. The eccentricity of ellipse lies between 0 to 1. 0≤e<1 The total sum of each distance from the locus of an ellipse to the two focal points is constant Ellipse has one major axis and one minor axis and a center ...
In mathematics, a hyperbola is an important conic section formed by the intersection of the double cone by a plane surface, but not necessarily at the center. A hyperbola is symmetric along the conjugate axis, and shares many similarities with the ellipse. Concepts like foci, directrix, latus ...
Equation of the parabola with focus (0,-3) and the directrix y=3 is: (a)x^(2)=-12y (b)x^(2)=12y (c)x^(2)=3y (d)x^(2)=-3y
