WebIn an ellipse with major axis 2a and minor axis 2b, the vertices on the major axis have the smallest radius of curvature of any points, R = b2 a; and the vertices on the minor axis have the largest radius of curvature of any points, R = a2 b. The ellipse's radius of curvature, as a function of parameter t [4] And as a function of θ WebAn ellipsoid is a surface that may be obtained from a sphere by deforming it by means of directional scalings, or more generally, of an affine transformation. An ellipsoid is a …

The semi-latus rectum is equal to the radius of curvature at the vertices (see section curvature ). Tangent [ edit] An arbitrary line intersects an ellipse at 0, 1, or 2 points, respectively called an exterior line, tangent and secant. Through any point of an ellipse there is a unique tangent. Meer weergeven 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 … Meer weergeven Standard equation The standard form of an ellipse in Cartesian coordinates assumes that the origin is the … Meer weergeven An ellipse possesses the following property: The normal at a point $${\displaystyle P}$$ bisects the angle between the lines Proof Meer weergeven An ellipse can be defined geometrically as a set or locus of points in the Euclidean plane: Given two … Meer weergeven Standard parametric representation Using trigonometric functions, a parametric representation of the standard ellipse Meer weergeven Each of the two lines parallel to the minor axis, and at a distance of $${\textstyle d={\frac {a^{2}}{c}}={\frac {a}{e}}}$$ from it, is called a directrix of the ellipse (see diagram).
