FORM is a symbolic manipulation system. It reads text files containing definitions of mathematical expressions as well as statements that tell it how to manipulate these expressions. Its original author is Jos Vermaseren of Nikhef, the Dutch institute for subatomic physics. It is widely used in the theoretical particle physics community, but it ...
Mathematical notation is widely used in mathematics, science, and engineering for representing complex concepts and properties in a concise, unambiguous, and accurate way. For example, the physicist Albert Einstein's formula = is the quantitative representation in mathematical notation of mass–energy equivalence. [1]
The order of acquisition is a concept in language acquisition describing the specific order in which all language learners acquire the grammatical features of their first language (L1). This concept is based on the observation that all children acquire their first language in a fixed, universal order, regardless of the specific grammatical ...
In computational mathematics, a word problem is the problem of deciding whether two given expressions are equivalent with respect to a set of rewriting identities. A prototypical example is the word problem for groups , but there are many other instances as well.
Instead, two related terms are used in morphology: lexeme and word-form [definition needed]. Generally, a lexeme is a set of inflected word-forms that is often represented with the citation form in small capitals. [8] For instance, the lexeme eat contains the word-forms eat, eats, eaten, and ate.
Form is the shape, visual appearance, or configuration of an object. In a wider sense, the form is the way something happens. Form may also refer to: Form (document), a document (printed or electronic) with spaces in which to write or enter data; Form (architecture), a combination of external appearance, internal structure, and the unity of the ...
In English, verbification typically involves simple conversion of a non-verb to a verb. The verbs to verbify and to verb, the first by derivation with an affix and the second by zero derivation, are themselves products of verbification (see autological word), and, as might be guessed, the term to verb is often used more specifically, to refer only to verbification that does not involve a ...
def – define or definition. deg – degree of a polynomial, or other recursively-defined objects such as well-formed formulas. (Also written as ∂.) del – del, a differential operator. (Also written as.) det – determinant of a matrix or linear transformation. DFT – discrete Fourier transform.
