Tangent lines to circles — In Euclidean plane geometry, tangent lines to circles form the subject of several theorems, and play an important role in many geometrical constructions and proofs. Since the tangent line to a circle at a point P is perpendicular to the radius to … Wikipedia
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
Tangent space — In mathematics, the tangent space of a manifold is a concept which facilitates the generalization of vectors from affine spaces to general manifolds, since in the latter case one cannot simply subtract two points to obtain a vector pointing from… … Wikipedia
Tangent cone — In geometry, the tangent cone is a generalization of the notion of the tangent space to a manifold to the case of certain spaces with singularities. Definition in convex geometry Let K be a closed convex subset of a real vector space V and part;… … Wikipedia
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 bundle — In mathematics, the tangent bundle of a smooth (or differentiable) manifold M , denoted by T ( M ) or just TM , is the disjoint unionThe disjoint union assures that for any two points x 1 and x 2 of manifold M the tangent spaces T 1 and T 2 have… … Wikipedia
Tangent circles — In geometry, tangent circles (also known as kissing circles) are circles that intersect in a single point. There are two types of tangency: internal and external. Many problems and constructions in geometry are related to tangent circles; such… … Wikipedia
Tangent half-angle formula — In various applications of trigonometry, it is useful to rewrite the trigonometric functions (such as sine and cosine) in terms of rational functions of a new variable t . These identities are known collectively as the tangent half angle formulae … Wikipedia
tangent — 1. noun /ˈtæn.dʒənt/ a) A straight line touching a curve at a single point without crossing it there. I believe we went off onto a tangent when we started talking about monkeys on unicycles at his retirement party. b) In a … Wiktionary
