The vertical bar is used as a special character in lightweight markup languages, notably MediaWiki 's Wikitext (in the templates and internal links). In LaTeX text mode, the vertical bar produces an em dash (—). The \textbar command can be used to produce a vertical bar.
Bar (music) In musical notation, a bar (or measure) is a segment of music bounded by vertical lines, known as bar lines (or barlines), usually indicating one of more recurring beats. The length of the bar, measured by the number of note values it contains, is normally indicated by the time signature.
Placing a vertical line through the turn symbol or inverting it, it indicates an inverted turn, in which the order of the auxiliary notes is reversed. Appoggiatura The first half of the principal note's duration has the pitch of the grace note (the first two-thirds if the principal note is a dotted note).
A vertical line is any line parallel to the vertical direction. A horizontal line is any line normal to a vertical line. Horizontal lines do not cross each other. Vertical lines do not cross each other. Not all of these elementary geometric facts are true in the 3-D context.
The distance (or perpendicular distance) from a point to a line is the shortest distance from a fixed point to any point on a fixed infinite line in Euclidean geometry. It is the length of the line segment which joins the point to the line and is perpendicular to the line. The formula for calculating it can be derived and expressed in several ways.
The lines and spaces are numbered from bottom to top; the bottom line is the first line and the top line is the fifth line. The musical staff is analogous to a mathematical graph of pitch with respect to time. Pitches of notes are given by their vertical position on the staff and notes are played from left to right.
e. In geometry, a straight line, usually abbreviated line, is an infinitely long object with no width, depth, or curvature, an idealization of such physical objects as a straightedge, a taut string, or a ray of light. Lines are spaces of dimension one, which may be embedded in spaces of dimension two, three, or higher.
List of anatomical lines. Axillary lines. Vertical lines: Midline, lateral sternal line, parasternal line and midclavicular line. Horizontal lines: Level of the sternal angle, and zipho-sternal line. Anatomical "lines", or "reference lines," are theoretical lines drawn through anatomical structures and are used to describe anatomical location.
