In digital typography, this depends on the font: Cambria and Calibri, for example, have underlined ordinal indicators, while most other fonts do not. Examples of the usage of ordinal indicators in Italian are: 1º, primo; 1ª, prima "first". 2º, secondo; 2ª, seconda "second". 3º, terzo; 3ª, terza "third".
Typographical symbols and punctuation marks are marks and symbols used in typography with a variety of purposes such as to help with legibility and accessibility, or to identify special cases. This list gives those most commonly encountered with Latin script .
Ordinal numbers may be written in English with numerals and letter suffixes: 1st, 2nd or 2d, 3rd or 3d, 4th, 11th, 21st, 101st, 477th, etc., with the suffix acting as an ordinal indicator. Written dates often omit the suffix, although it is nevertheless pronounced. For example: 5 November 1605 (pronounced "the fifth of November ...
The second, symbol s, is the SI unit of time. It is defined by taking the fixed numerical value of the caesium frequency, Δν Cs, the unperturbed ground-state hyperfine transition frequency of the caesium 133 atom, to be 9 192 631 770 when expressed in the unit Hz, which is equal to s −1.
The SI comprises a coherent system of units of measurement starting with seven base units, which are the second (symbol s, the unit of time ), metre (m, length ), kilogram (kg, mass ), ampere (A, electric current ), kelvin (K, thermodynamic temperature ), mole (mol, amount of substance ), and candela (cd, luminous intensity ).
That is, when the first goes up, the second goes down the same number of diatonic steps (with some chromatic alteration); and when the first goes down, the second goes up the same number of steps. In music theory, an inversion is a rearrangement of the top-to-bottom elements in an interval, a chord, a melody, or a group of contrapuntal lines of ...
This is a suggestive notational device that comes from formal manipulations of symbols, as in, d ( d y d x ) d x = ( d d x ) 2 y = d 2 y d x 2 . {\displaystyle {\frac {d\left({\frac {dy}{dx}}\right)}{dx}}=\left({\frac {d}{dx}}\right)^{2}y={\frac {d^{2}y}{dx^{2}}}.}
t. e. In heraldry, cadency is any systematic way to distinguish arms displayed by descendants of the holder of a coat of arms when those family members have not been granted arms in their own right. Cadency is necessary in heraldic systems in which a given design may be owned by only one person at any time, generally the head of the senior line ...
The second derivative generalizes to higher dimensions through the notion of second partial derivatives. For a function f : R 3 → R , these include the three second-order partials ∂ 2 f ∂ x 2 , ∂ 2 f ∂ y 2 , and ∂ 2 f ∂ z 2 {\displaystyle {\frac {\partial ^{2}f}{\partial x^{2}}},\;{\frac {\partial ^{2}f}{\partial y^{2}}},{\text ...
Moment (mathematics) In mathematics, the moments of a function are certain quantitative measures related to the shape of the function's graph. If the function represents mass density, then the zeroth moment is the total mass, the first moment (normalized by total mass) is the center of mass, and the second moment is the moment of inertia.
