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 …

Oct 6, 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.

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)

Nov 14, 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 …

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 …

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.

2 days ago · The key features of the ellipse are its center, vertices, co-vertices, foci, and lengths and positions of the major and minor axes. Just as with other equations, we can identify all of …

Nov 1, 2025 · Definition of an Ellipse An ellipse is the set of all points in a plane such that the sum of their distances from two fixed points, called foci, is constant.
