Parabola - Wikipedia
In mathematics, a parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped. It fits several superficially different mathematical descriptions, which can all be proved to define exactly the same curves. One description of a parabola involves a point (the focus) and a line (the directrix).
Parabola - Formula, Graphing, Examples | Parabola Equation
A parabola is the locus of a point that is equidistant from a fixed point called the focus (F), and the fixed-line is called the Directrix (x + a = 0). Let us consider a point P(x, y) on the parabola, and using the formula PF = PM, we can find the equation of the parabola.
Parabola - Math is Fun
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)
What are parabolas, their equations, their rules? | Purplemath
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".
Parabola - Math.net
Parabola. A parabola is the characteristic U-shaped curve of a quadratic equation. A parabola can be used to model many real-world phenomena. For example, when you shoot a basketball, the path of the ball creates a parabola. Below are two parabola graph examples, one in which the parabola opens upwards and one in which it opens downwards:
Parabola -- from Wolfram MathWorld
6 天之前 · A parabola (plural "parabolas"; Gray 1997, p. 45) is the set of all points in the plane equidistant from a given line L (the conic section directrix) and a given point F not on the line (the focus). 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 ...
Parabola – Graph, Properties, Examples & Equation of Parabola
2024年9月3日 · Parabola is a fundamental concept in mathematics and geometry. It is one of the conic sections in Maths which is formed by an intersection of a surface plane and a double-napped cone. A parabola is a U-shaped curve that can be either concave up or down, depending on the equation.
5.2: The Equation of the Parabola - Mathematics LibreTexts
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.
Parabola – Properties, Components, and Graph - The Story of …
Parabolas are curves that contain points where their distances from the focus and their distances from the directrix will always be equal. The model below can help us visualize what this definition means. A parabola will contain three important elements: a focus, a directrix, and a vertex.
