Latin and Greek letters are used in mathematics, science, engineering, and other areas where mathematical notation is used as symbols for constants, special functions, and also conventionally for variables representing certain quantities.
The abstract cyclic group of order n, when written additively, has notation Z n, or in contexts where there may be confusion with p-adic integers, Z/nZ; when written multiplicatively, e.g. as roots of unity, C n is used (this does not affect the notation of isometry groups called C n).
TeX is a mathematically oriented typesetting system that was created in 1978 by Donald Knuth. It is widely used in mathematics, through its extension called LaTeX, and is a de facto standard. (The above expression is written in LaTeX.) More recently, another approach for mathematical typesetting is provided by MathML. However, it is not well ...
(Also written as arcexcsc, arcexc.) arcexcsc – inverse excosecant function. (Also written as arcexcosec, arcexc.) arcexs – inverse exsecant function. (Also written as arcexsec.) arcexsec – inverse exsecant function. (Also written as arcexs.) arcosech – inverse hyperbolic cosecant function. (Also written as arcsch.) arcosh – inverse ...
Writing systems are used to record human language, and may be classified according to certain common features.. The usual name of the script is given first; the name of the languages in which the script is written follows (in brackets), particularly in the case where the language name differs from the script name.
Some written languages are more consistent in their correlation of written symbols (or graphemes) with sound (or phonemes), and are therefore considered to have better phonemic orthography. Ideographic writing, by definition, refers to things or ideas independently of their pronunciation in any language.
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.
The consequence of these features is that a mathematical text is generally not understandable without some prerequisite knowledge. For example, the sentence "a free module is a module that has a basis" is perfectly correct, although it appears only as a grammatically correct nonsense, when one does not know the definitions of basis, module, and free module.
