In natural language semantics, denotations are conceived of as the outputs of the semantic component of the grammar.For example, the denotation of the word "blue" is the property of being blue and the denotation of the word "Barack Obama" is the person who goes by that name.
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
230 V (Typically denoted on domestic electricals as the older 240 V standard) AC electric current, provided by the electricity grid to homes and businesses; also attrib. ("mains cable") (US: 120 volts AC, variously called: line power, grid power, AC power, household electricity, etc.)
If is a member of , then the image of under , denoted (), is the value of when applied to . is alternatively known as the output of for argument . Given y , {\displaystyle y,} the function f {\displaystyle f} is said to take the value y {\displaystyle y} or take y {\displaystyle y} as a value if there exists some x {\displaystyle x} in the ...
If A and B are sets and every element of A is also an element of B, then: . A is a subset of B, denoted by , or equivalently,; B is a superset of A, denoted by .; If A is a subset of B, but A is not equal to B (i.e. there exists at least one element of B which is not an element of A), then:
with domain, the range of , sometimes denoted or (), [4] may refer to the codomain or target set (i.e., the set into which all of the output of is constrained to fall), or to (), the image of the domain of under (i.e., the subset of consisting of all actual outputs of ). The image of a function is always a subset of the codomain of the ...
Variables are generally denoted by a single letter, most often from the Latin alphabet and less often from the Greek, which may be lowercase or capitalized. The letter may be followed by a subscript: a number (as in x 2 ), another variable ( x i ), a word or abbreviation of a word as a label ( x total ) or a mathematical expression ( x 2 i +1 ).
In SI units, it is measured in radians per second squared (rad/s 2), and is usually denoted by the Greek letter alpha (α). [12] Just like angular velocity, there are two types of angular acceleration: spin angular acceleration and orbital angular acceleration, representing the time rate of change of spin angular velocity and orbital angular ...
