Elliptical may mean: having the shape of an ellipse, or more broadly, any oval shape in botany, having an elliptic leaf shape; of aircraft wings, having an elliptical planform; characterised by ellipsis (the omission of words), or by concision more broadly; elliptical trainer, an exercise machine
In astrodynamics or celestial mechanics, an elliptic orbit or elliptical orbit is a Kepler orbit with an eccentricity of less than 1; this includes the special case of a circular orbit, with eccentricity equal to 0. In a stricter sense, it is a Kepler orbit with the eccentricity greater than 0 and less than 1 (thus excluding the circular orbit).
The giant elliptical galaxy ESO 325-4. An elliptical galaxy is a type of galaxy with an approximately ellipsoidal shape and a smooth, nearly featureless image. They are one of the three main classes of galaxy described by Edwin Hubble in his Hubble sequence and 1936 work The Realm of the Nebulae, [1] along with spiral and lenticular galaxies.
An elliptical machine may be more challenging to use for individuals with balance or coordination problems, which could result in injuries. That said, injuries resulting from tripping on or ...
Combine elliptical training with upper-body exercises to increase calorie burn and engage more muscles. Incorporate intervals of arm movements, such as pushing and pulling the handles while pedaling.
where (h, k) is the center of the ellipse in Cartesian coordinates, in which an arbitrary point is given by (x, y).The semi-major axis is the mean value of the maximum and minimum distances and of the ellipse from a focus — that is, of the distances from a focus to the endpoints of the major axis
For those looking to work out at home, elliptical machines are the top choice for many fitness fanatics who prefer to keep the gym as close to them as possible — AKA their home. Most ellipticals ...
Elliptical distribution, in statistics; Flattening, also called ellipticity and oblateness, is a measure of the compression of a circle or sphere along a diameter to form an ellipse or an ellipsoid of revolution (spheroid), respectively. Focaloid, a shell bounded by two concentric, confocal ellipsoids; Geodesics on an ellipsoid
