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 circle, which is …

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.

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)

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 and 'b' is the length …

Dec 3, 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 two …

Feb 12, 2025 · An ellipse is a geometric figure defined by its constant distances from any point on its curve to two fixed points known as its foci (Foci). Simply put, it consists of all points in the plane that …

May 16, 2025 · An ellipse is the set of all points in a plane where the sum of the distances to two fixed points (foci) is constant.

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

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 points, …

An ellipse is a closed curve in a plane created by cutting a cone with a plane at an angle that is not parallel to the base. It looks like a stretched circle and has two focal points.
