[1] [2] The terms mathematical constant or physical constant are sometimes used to distinguish this meaning. [3] A function whose value remains unchanged (i.e., a constant function). [4] Such a constant is commonly represented by a variable which does not depend on the main variable(s) in question.
The negative meaning was carried on into French and ultimately English. [27] Latin nimius means "excessive, too much". It maintained this meaning in Spanish nimio, but it was also misinterpreted as "insignificant, without importance". [28] [10]
A mathematical constant is a key number whose value is fixed by an unambiguous definition, often referred to by a symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems. [1]
A more explicit way to denote this function is x ↦ ax 2 + bx + c, which clarifies the function-argument status of x and the constant status of a, b and c. Since c occurs in a term that is a constant function of x, it is called the constant term. [21] Specific branches and applications of mathematics have specific naming conventions for ...
Physical constant, a physical quantity generally believed to be universal and unchanging; Constant (computer programming), a value that, unlike a variable, cannot be reassociated with a different value; Logical constant, a symbol in symbolic logic that has the same meaning in all models, such as the symbol "=" for "equals"
The constants listed here are known values of physical constants expressed in SI units; that is, physical quantities that are generally believed to be universal in nature and thus are independent of the unit system in which they are measured.
The term antonym (and the related antonymy) is commonly taken to be synonymous with opposite, but antonym also has other more restricted meanings. Graded (or gradable) antonyms are word pairs whose meanings are opposite and which lie on a continuous spectrum (hot, cold).
A thesaurus (pl.: thesauri or thesauruses), sometimes called a synonym dictionary or dictionary of synonyms, is a reference work which arranges words by their meanings (or in simpler terms, a book where one can find different words with similar meanings to other words), [1] [2] sometimes as a hierarchy of broader and narrower terms, sometimes simply as lists of synonyms and antonyms.
