Parabola Equation. The general equation of a parabola is: y = a (x-h) 2 + k or x = a (y-k) 2 +h, where (h,k) denotes the vertex. The standard equation of a regular parabola is y 2 = 4ax. Some of the important terms below are helpful to understand the features and parts of a parabola y 2 = 4ax.
For a parametric equation of a parabola in general position see § As the affine image of the unit parabola. The implicit equation of a parabola is defined by an irreducible polynomial of degree two: + + + + + =, such that =, or, equivalently, such that + + is the square of a linear polynomial.
The simplest equation for a parabola is y = x2. Turned on its side it becomes y2 = x. (or y = √x for just the top half) A little more generally: y 2 = 4ax. where a is the distance from the origin to the focus (and also from the origin to directrix) Example: Find the focus for the equation y 2 =5x.
A parabola is defined as the locus (or collection) of points equidistant from a given point (the focus) and a given line (the directrix). Another important point is the vertex or turning point of the parabola. If the equation of a parabola is given in standard form then the vertex will be (h, k).
What is a parabola? A parabola is a particular type of geometrical curve which, algebraically, corresponds to a quadratic equation. In geometrical terms, the parabola corresponds to the edge of slice of an inverted cone; this slice is what is called the conic "section".
28 Σεπ 2024 · Equations. The equation of a parabola depends on its orientation, the position of its vertex, and whether it is centered at the origin or elsewhere. Standard Form. A horizontal parabola is a parabola that opens sideways, either to the left or to the right. y 2 = 4ax. Here, The equation of the axis of symmetry is y = 0; The equation of directrix ...
General Equations of Parabola. The general equation of a parabola is given by y = a(x – h) 2 + k or x = a(y – k) 2 +h. Here, (h, k) denotes the vertex. y = a(x – h) 2 + k is the regular form. x = a(y – k) 2 +h is the sidewise form. Position of a point with respect to the parabola
