In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of both distances to the two focal points is a constant. It generalizes a …

An ellipse is the locus of a point whose sum of distances from two fixed points is a constant. Its equation is of the form x^2/a^2 + y^2/b^2 = 1, where 'a' is the length of the semi-major axis …

An ellipse usually looks like a squashed circle ... F is a focus, G is a focus, and together they are called foci. (pronounced fo-sigh)

Dec 24, 2025 · Ellipse, a closed curve, the intersection of a right circular cone (see cone) and a plane that is not parallel to the base, the axis, or an element of the cone.

Dec 22, 2025 · The ellipse is a conic section and a Lissajous curve. An ellipse can be specified in the Wolfram Language using Circle [x, y, a, b]. If the endpoints of a segment are moved along …

A closed curve consisting of points whose distances from each of two fixed points (foci) all add up to the same value is an ellipse. The midpoint between the foci is the center.

Aug 3, 2023 · An ellipse is a closed curved plane formed by a point moving so that the sum of its distance from the two fixed or focal points is always constant. It is formed around two focal …

An ellipse is a conic section, that resembles an oval, but is formally characterized by the following property: there exist two points ...

An ellipse differs from an oval in that an oval, being egg-shaped, is "flatter" on one end than on the other; an ellipse is equally rounded on each of its ends.
