When f is a function of several variables, it is common to use "∂", a stylized cursive lower-case d, rather than "D". As above, the subscripts denote the derivatives that are being taken. For example, the second partial derivatives of a function f(x, y) are: [6]
Corner quotes, also called “Quine quotes”; for quasi-quotation, i.e. quoting specific context of unspecified (“variable”) expressions; [4] also used for denoting Gödel number; [5] for example “⌜G⌝” denotes the Gödel number of G. (Typographical note: although the quotes appears as a “pair” in unicode (231C and 231D), they ...
The apostrophe must not be used to indicate the possessive except – although not mandatory – when there is already an s, x or z present in the base form, as in Lukas' bok. Welsh uses the apostrophe to mark elision of the definite article yr ('the') following a vowel (a, e, i, o, u, y, or, in Welsh, w), as in i'r tŷ, 'to the house'.
2. Denotes the additive inverse and is read as minus, the negative of, or the opposite of; for example, –2. 3. Also used in place of \ for denoting the set-theoretic complement; see \ in § Set theory. × (multiplication sign) 1. In elementary arithmetic, denotes multiplication, and is read as times; for example, 3 × 2. 2.
Associate degrees are also offered by some universities, as a final degree or as an intermediate stage before a bachelor degree. In Hispanic America, an associate degree is called a carrera técnica, tecnicatura or Técnico Superior Universitario (TSU), while a bachelor's degree would be known as a licenciatura or ingeniería.

Any such symbol can be called a decimal mark, decimal marker, or decimal sign. Symbol-specific names are also used; decimal point and decimal comma refer to a dot (either baseline or middle ) and comma respectively, when it is used as a decimal separator; these are the usual terms used in English, [ 1 ] [ 2 ] [ 3 ] with the aforementioned ...
A derivative or differentiated function: in Lagrange's notation, f ′ (x) and f ″(x) are the first and second derivatives of f (x) with respect to x. Likewise are f ‴(x) and f ⁗(x). Similarly, if y = f (x), then y ′ and y″ are the first and second derivatives of y with respect to x. Other notation for derivatives also exists (see ...
