The tangent plane to a surface at a given point p is defined in an analogous way to the tangent line in the case of curves. It is the best approximation of the surface by a plane at p , and can be obtained as the limiting position of the planes passing through 3 distinct points on the surface close to p as these points converge to p .
Basis of trigonometry: if two right triangles have equal acute angles, they are similar, so their corresponding side lengths are proportional.. In mathematics, the trigonometric functions (also called circular functions, angle functions or goniometric functions) [1] are real functions which relate an angle of a right-angled triangle to ratios of two side lengths.
Trigonometry (from Ancient Greek τρίγωνον (trígōnon) ' triangle ' and μέτρον (métron) ' measure ') [1] is a branch of mathematics concerned with relationships between angles and side lengths of triangles.
A tangent line t to a circle C intersects the circle at a single point T. For comparison, secant lines intersect a circle at two points, whereas another line may not intersect a circle at all. This property of tangent lines is preserved under many geometrical transformations, such as scalings, rotation, translations, inversions, and map ...
Tangent (clavichord), a part of the action of the clavichord that both initiates and sustains a tone, and helps determine pitch Tangent (tangent piano), a part of the action of the tangent piano that only initiates the sound by striking the string(s) and rebounding immediately in the manner of a piano
The tangent space may then be defined as the dual space of /. While this definition is the most abstract, it is also the one that is most easily transferable to other settings, for instance, to the varieties considered in algebraic geometry.

In projective geometry and related contexts, an asymptote of a curve is a line which is tangent to the curve at a point at infinity. [ 1 ] [ 2 ] The word asymptote is derived from the Greek ἀσύμπτωτος ( asumptōtos ) which means "not falling together", from ἀ priv. + σύν "together" + πτωτ-ός "fallen". [ 3 ]
