tangent — /tan jeuhnt/, adj. 1. in immediate physical contact; touching. 2. Geom. a. touching at a single point, as a tangent in relation to a curve or surface. b. in contact along a single line or element, as a plane with a cylinder. 3. tangential (def.… … Universalium
Tangent — For the tangent function see trigonometric functions. For other uses, see tangent (disambiguation). In geometry, the tangent line (or simply the tangent) to a curve at a given point is the straight line that just touches the curve at that point… … Wikipedia
Courbes planes — Courbe plane En géométrie, une courbe plane est une courbe qui est entièrement contenue dans un (unique) plan, et qui est identifiable à une fonction continue : où I est un intervalle de l ensemble des nombres réels. L image d une courbe est … Wikipédia en Français
Lower tangent arc — A lower tangent arc is a rarely observable halo, an optical phenomenon appearing under and tangent to a 22° halo centred around the sun.Just like upper tangent arcs, the shape of a lower tangent arc is dependent on the altitude of the sun. As the … Wikipedia
Affine connection — An affine connection on the sphere rolls the affine tangent plane from one point to another. As it does so, the point of contact traces out a curve in the plane: the development. In the branch of mathematics called differential geometry, an… … Wikipedia
Cartan connection — In the mathematical field of differential geometry, a Cartan connection is a flexible generalization of the notion of an affine connection. It may also be regarded as a specialization of the general concept of a principal connection, in which the … Wikipedia

Monge cone — In the mathematical theory of partial differential equations (PDE), the Monge cone is a geometrical object associated with a first order equation. It is named for Gaspard Monge. In two dimensions, let be a PDE for an unknown real valued function… … Wikipedia
Differential geometry — A triangle immersed in a saddle shape plane (a hyperbolic paraboloid), as well as two diverging ultraparallel lines. Differential geometry is a mathematical discipline that uses the techniques of differential and integral calculus, as well as… … Wikipedia
Envelope (mathematics) — In mathematics, an envelope of a family of manifolds (especially a family of curves) is a manifold that is tangent to each member of the family at some point.Envelope of a family of curvesThe simplest formal expression for an envelope of curves… … Wikipedia
Curve of constant width — A Reuleaux triangle is a curve of constant width. The sides of the square are supporting lines: each touches the curve but does not intersect the interior. The Reuleaux triangle can be rotated whilst always touching each side of the square in a… … Wikipedia
