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.
A parabola is a curve that has a fixed point (focus) and a fixed line (directrix) such that any point on the curve is equidistant from both. Learn how to draw, reflect, and measure parabolas, and see how they are related to cones and projectiles.
A parabola is a U-shaped curve that results from the collection of points equidistant from a focus and a directrix. Learn how to find the focus, directrix, vertex, axis of symmetry, eccentricity, and focal length of a parabola, and how to write and sketch its equation.
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.
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 · A parabola is a U-shaped curve that is also found in the path of water in a fountain or the shape of satellite dishes. Mathematically, it is the graph of a quadratic function in two variables, y = ax 2 + bx + c, that can be defined as the set of all points that are equidistant from a fixed point, called the focus , and a fixed line, called the ...
A special curve that can look like an arch. On a parabola any point is at an equal distance from... ...a fixed point (the focus), and ... ...a fixed straight line (the directrix). It is one of the "Conic Sections" See: Conic Section. Parabola. Illustrated definition of Parabola: A special curve that can look like an arch.
