Glossary of mathematical symbols. 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 ...

LaTeX (/ ˈ l ɑː t ɛ k / ⓘ LAH-tek or / ˈ l eɪ t ɛ k / LAY-tek, [2] [Note 1] often stylized with vertically offset letters) is a software system for typesetting documents. [3] LaTeX markup describes the content and layout of the document, as opposed to the formatted text found in WYSIWYG word processors like Microsoft Word, LibreOffice Writer and Apple Pages.
Approximation theory is a branch of mathematics, and a quantitative part of functional analysis. Diophantine approximation deals with approximations of real numbers by rational numbers . Approximation usually occurs when an exact form or an exact numerical number is unknown or difficult to obtain.
The nabla symbol. The nabla is a triangular symbol resembling an inverted Greek delta: [ 1] or ∇. The name comes, by reason of the symbol's shape, from the Hellenistic Greek word νάβλα for a Phoenician harp, [ 2][ 3] and was suggested by the encyclopedist William Robertson Smith in an 1870 letter to Peter Guthrie Tait.

The integral symbol is U+222B ∫ INTEGRAL in Unicode [ 5] and \int in LaTeX. In HTML, it is written as ∫ ( hexadecimal ), ∫ ( decimal) and ∫ ( named entity ). The original IBM PC code page 437 character set included a couple of characters ⌠ and ⌡ (codes 244 and 245 respectively) to build the integral symbol.
Since the symmetric group S 2 of degree 2 is isomorphic to the hyperoctahedral group is a special case of a generalized symmetric group. [ 6 ] The smallest non-trivial wreath product is Z 2 ≀ Z 2 {\displaystyle \mathbb {Z} _{2}\wr \mathbb {Z} _{2}} , which is the two-dimensional case of the above hyperoctahedral group.
