For example, \text {ð} and \text {þ} (used in Icelandic) will give errors. The normal way of entering quotation marks in text mode (two back ticks for the left and two apostrophes for the right), such as \text { a ``quoted'' word } will not work correctly.
A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula. As formulas are entirely constituted with symbols of various types, many symbols are needed for ...
Deutsch: Dieses Dokument listet 20323 Symbole und die dazugehörigen LaTeX-Befehle auf. Manche Symbole sind in jedem LaTeX-2ε-System verfügbar; andere benötigen zusätzliche Schriftarten oder Pakete, die nicht notwendig in jeder Distribution mitgeliefert werden und daher selbst installiert werden müssen.
The following table lists many common symbols, together with their name, how they should be read out loud, and the related field of mathematics. Additionally, the subsequent columns contains an informal explanation, a short example, the Unicode location, the name for use in HTML documents, [1] and the LaTeX symbol.
The triple bar character in Unicode is code point U+2261 ≡ IDENTICAL TO (≡, ≡). [1] The closely related code point U+2262 ≢ NOT IDENTICAL TO (≢, ≢) is the same symbol with a slash through it, indicating the negation of its mathematical meaning.
The UK/Ireland keyboard has both symbols engraved: the broken bar is given as an alternate graphic on the "grave" key; the solid bar is on the backslash key. The broken bar character can be typed (depending on the layout) as AltGr + ` or AltGr + 6 or AltGr + ⇧ Shift + \ on Windows and Compose ! ^ on Linux.
Some variants of X-bar notation use a double-bar (or double-prime) to represent phrasal-level units. X-bar theory derives its name from the overbar. One of the core proposals of the theory was the creation of an intermediate syntactic node between phrasal (XP) and unit (X) levels; rather than introduce a different label, the intermediate unit ...
The default sans-serif may render certain characters indistinguishable, such as 1, I and l. In articles mixing raw wiki with <math> formulae, the appearance of the same variable in the two types of formula does not match (serif vs sans-serif). {} ('texhtml' class) Distinguishes a formula from the running text.
