In geometry, the tangent line (or simply tangent) to a plane curve at a given point is the straight line that "just touches" the curve at that point.
In mathematics, the tangent space of a manifold facilitates the generalization of vectors from affine spaces to general manifolds, since in the latter
Tangent Comics is a DC Comics imprint created in 1997, developed from ideas by Dan Jurgens. The line, formed from various one-shots, focused on creating
of tangent vectors, see tangent space. In mathematics, a tangent vector is a vector that is tangent to a curve or surface at a given point. Tangent vectors
most widely used in modern mathematics are the sine, the cosine, and the tangent. Their reciprocals are respectively the cosecant, the secant, and the cotangent
