ellipse    音标拼音: [ɪl'ɪps]
n. 椭圆形,椭圆,
n. 椭圆

椭圆形,椭圆,椭圆

ellipse
椭图形

ellipse
n 1: a closed plane curve resulting from the intersection of a
circular cone and a plane cutting completely through it;
"the sums of the distances from the foci to any point on an
ellipse is constant" [synonym: {ellipse}, {oval}]

Ellipse \El*lipse"\ ([e^]l*l[i^]ps"), n. [Gr. 'e`lleipsis,
prop., a defect, the inclination of the ellipse to the base
of the cone being in defect when compared with that of the
side to the base: cf. F. ellipse. See {Ellipsis}.]
1. (Geom.) An oval or oblong figure, bounded by a regular
curve, which corresponds to an oblique projection of a
circle, or an oblique section of a cone through its
opposite sides. The greatest diameter of the ellipse is
the major axis, and the least diameter is the minor axis.
See {Conic section}, under {Conic}, and cf. {Focus}.
[1913 Webster]

2. (Gram.) Omission. See {Ellipsis}.
[1913 Webster]

3. The elliptical orbit of a planet.
[1913 Webster]

The Sun flies forward to his brother Sun;
The dark Earth follows wheeled in her ellipse.
--Tennyson.

  • Ellipse by LegXercise
    That's why we created Ellipse with a 46% larger Rotational Diameter than any other seated elliptical in the world, this provides more Exercise and Range of Motion that's also Super Low Impact, Ultra Smooth and Feels Great!
  • Ellipse - Wikipedia
    In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant It generalizes a circle, which is the special type of ellipse in which the two focal points are the same
  • Ellipse - Equation, Formula, Properties, Graphing - Cuemath
    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 of the semi-minor axis
  • Ellipse - Math is Fun
    We also get an ellipse when we slice through a cone (but not too steep a slice, or we get a parabola or hyperbola) In fact the ellipse is a conic section (a section of a cone) with an eccentricity between 0 and 1
  • Ellipse | Definition, Properties Equations | Britannica
    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
  • Definition - BYJUS
    The shape of the ellipse is in an oval shape and the area of an ellipse is defined by its major axis and minor axis Area of ellipse = πab , where a and b are the length of semi-major and semi-minor axis of an ellipse
  • 8. 2: The Ellipse - Mathematics LibreTexts
    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 these features …
  • 5. The Ellipse - Interactive Mathematics
    In this section, we learn the properties of an ellipse, the equation of an ellipse and some applications
  • Ellipse -- from Wolfram MathWorld
    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 intersecting lines, a fixed point on the segment (or on the line that prolongs it) describes an arc of an ellipse
  • What Is an Ellipse? Properties, Formulas Applications
    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 satisfy this unique condition
