A tangent bundle is the collection of all of the tangent spaces for all points on a manifold, structured in a way that it forms a new manifold itself....

In solid mechanics, the tangent modulus is the slope of the stress–strain curve at any specified stress or strain. Below the proportional limit (the limit...

most widely used in modern mathematics are the sine, the cosine, and the tangent functions. Their reciprocals are respectively the cosecant, the secant...

Tangent arcs are a type of halo, an atmospheric optical phenomenon, which appears above and below the observed Sun or Moon, tangent to the 22° halo. To...

geometry, a tangent line to a circle is a line that touches the circle at exactly one point, never entering the circle's interior. Tangent lines to circles...

Tangent is a city in Linn County, Oregon, United States. The population was 1,231 at the 2020 census. Tangent was the site of a railway station on the...

Look up tangent in Wiktionary, the free dictionary. A tangent, in geometry, is a straight line through a point on a curve that has the same direction...

vertical tangent is a tangent line that is vertical. Because a vertical line has infinite slope, a function whose graph has a vertical tangent is not differentiable...

Therefore, the expression on the right-hand side is just the equation for the tangent line to the graph of f {\displaystyle f} at ( a , f ( a ) ) {\displaystyle...

In Euclidean geometry, the tangent-secant theorem describes the relation of line segments created by a secant and a tangent line with the associated circle...

geometry, tangent circles (also known as kissing circles) are circles in a common plane that intersect in a single point. There are two types of tangency: internal...

Tangent Comics is a DC Comics imprint created in 1997, developed from ideas by Dan Jurgens. The line, formed from 18 one-shots, focused on creating all-new...

pushforward is a linear approximation of smooth maps (formulating manifold) on tangent spaces. Suppose that φ : M → N {\displaystyle \varphi \colon M\to N} is...

Tangent is a social networking organisation for ladies aged over 45, primarily intended for former members of Ladies Circle. It is part of the Round Table...

hemisphere. A tangent ogive nose is often blunted by capping it with a segment of a sphere. The tangency point where the sphere meets the tangent ogive can...

manifold. The fibre of the holomorphic tangent bundle over a point is the holomorphic tangent space, which is the tangent space of the underlying smooth manifold...

tangents can always be drawn to a circle from any point outside the circle, and these tangents are equal in length. If a tangent at A and a tangent at...

Local tangent plane coordinates (LTP) are part of a spatial reference system based on the tangent plane defined by the local vertical direction and the...

trigonometry, tangent half-angle formulas relate the tangent of half of an angle to trigonometric functions of the entire angle. The tangent of half an angle...
