Note: The principal vertex of a conic section is, in the parabola, the vertex of the axis of the curve: in the ellipse, either extremity of either axis, but usually the left-hand vertex of the transverse axis; in the hyperbola, either vertex, but usually the right-hand vertex of the transverse axis.
Vertex of a curve (Math.), the point in which the axis of the curve intersects it.
Vertex of an angle (Math.), the point in which the sides of the angle meet.
Vertex of a solid, or Vertex of a surface of revolution (Math.), the point in which the axis pierces the surface.
Douglas Harper's Etymology Dictionary
1560s, "the point opposite the base in geometry," from Latin vertex "highest point," literally "the turning point," originally "whirling column, whirlpool," from vertere "to turn" (see versus). Meaning "highest point of anything" is first attested 1640s.

Vertex ( Latin: peak; plural vertices or vertexes) means the "top", or the highest point of something. It may refer to:
In mathematics, and more specifically in graph theory, a vertex (plural vertices) or node is the fundamental unit of which graphs are formed: an undirected graph consists of a set of vertices and a set of edges (unordered pairs of vertices), while a directed graph consists of a set of vertices and a set of arcs (ordered pairs of vertices). In a diagram of a graph, a vertex is usually represented by a circle with a label, and an edge is represented by a line or arrow extending from one vertex to another.
From the point of view of graph theory, vertices are treated as featureless and indivisible objects, although they may have additional structure depending on the application from which the graph arises; for instance, a semantic network is a graph in which the vertices represent concepts or classes of objects.
The two vertices forming an edge are said to be the endpoints of this edge, and the edge is said to be incident to the vertices. A vertex w is said to be adjacent to another vertex v if the graph contains an edge (v,w). The neighborhood of a vertex v is an induced subgraph of the graph, formed by all vertices adjacent to v.
Vertex is a studio album by Canadian hip hop musician Buck 65. The album contains themes of Greek Mythology, fame, sleep deprivation and baseball.
In the geometry of planar curves, a vertex is a point of where the first derivative of curvature is zero. This is typically a local maximum or minimum of curvature, and some authors define a vertex to be more specifically a local extreme point of curvature. However, other special cases may occur, for instance when the second derivative is also zero, or when the curvature is constant. For space curves, on the other hand, a vertex is a point where the torsion vanishes.
A vertex (plural vertices) in computer graphics is a data structure that describes certain attributes, like the position of a point in 2D or 3D space, at multiple points on a surface.
Vertex was a band formed in 1995 featuring singer Stephen Pearcy ( Ratt, Arcade, Vicious Delite, Nitronic), guitarist Al Pitrelli ( Danger Danger, Hotshot, Alice Cooper, Asia, Savatage, Megadeth, Trans-Siberian Orchestra), and drummer Hiro Kuretani (WXXI, Trancentral Station).
They released a self-titled album in 1996 as well as a single for the track "One Like a Son" that included two remixes by Eric Caudieux and Stan Katayama. A video for this single was also released. All bass parts were played by Pitrelli, who also recorded keyboards. Bob Daisley played bass on tracks "Time and Time" and "Ain't Gonna Be".
Kuretani, who had met Stephen Pearcy at a gig where he opened for Stephen's band Arcade. Bassist Robbie Crane was a touring bassist for Vertex, but was not on the band's album. The band's music is categorized as industrial rock.
Stephen Pearcy and Robbie Crane are currently playing together in Ratt. Hiro Kuretani went on to become an electronic music ( progressive breaks) producer.
