  • Parabola - Math is Fun
    A parabola is a curve where any point is at an equal distance from: Get a piece of paper, draw a straight line on it, then make a big dot for the focus (not on the line!) Now play around with some measurements until you have another dot that is exactly the same distance from the focus and the straight line
  • 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)
  • 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 - Formula, Graphing, Examples | Parabola Equation - Cuemath
    Here are the formulas to find the equation of the axis, directrix, vertex, focus, and length of the latus rectum of different types of parabolas
  • Graph, Properties, Examples Equation of Parabola - GeeksforGeeks
    In this article, we will understand what a parabola is, its graph and properties, examples, and the Equation of a Parabola, and others in detail A parabola is a symmetrical curve that is defined as the set of all points that are equidistant from a fixed point (the focus) and a fixed straight line (the directrix)
  • Parabola - Math. net
    The precise parabola definition is: a collection of points such that the distance from each point on the curve to a fixed point (the focus) and a fixed straight line (the directrix) is equal The figure below shows the various parts of a parabola as well as some important terms Focus - the fixed point of a parabola
  • 11. 3: Parabolas - Mathematics LibreTexts
    A parabola is all points in a plane that are the same distance from a fixed point and a fixed line The fixed point is called the focus, and the fixed line is called the directrix of the parabola Previously, we learned to graph vertical parabolas from the general form or the standard form using properties Those methods will also work here
  • Parabola – Properties, Components, and Graph - The Story of Mathematics
    Parabolas are the U-shaped conics that represent quadratic expressions These are the result of a cone being sliced through diagonally by a plane Parabolas are used to model projectile motions and the shape of reflectors
