However, some authors such as Diophantus used some symbols as abbreviations. The first systematic use of formulas, and, in particular the use of symbols for unspecified numbers is generally attributed to François Viète (16th century). However, he used different symbols than those that are now standard.
Babylonian mathematics were written using a sexagesimal (base-60) numeral system. From this derives the modern-day usage of 60 seconds in a minute, 60 minutes in an hour, and 360 (60 × 6) degrees in a circle, as well as the use of minutes and seconds of arc to denote fractions of a degree. Babylonian advances in mathematics were facilitated by ...
When defining a term, do not use the phrase "if and only if". For example, instead of A function f is even if and only if f(−x) = f(x) for all x; write A function f is even if f(−x) = f(x) for all x. If it is reasonable to do so, rephrase the sentence to avoid the use of the word "if" entirely. For example,
Sibilance is used most successfully in stanzas one and five. The writer uses sibilance to imitate the sound and atmosphere she describes. In stanza one, she is imitating the "silent sign," and in stanza five she is trying to create a serene atmosphere that is "soft" and "sweetly spoke" by using the soft "s" sound repeatedly.
Greek letters are used in mathematics, science, engineering, and other areas where mathematical notation is used as symbols for constants, special functions, and also conventionally for variables representing certain quantities. In these contexts, the capital letters and the small letters represent distinct and unrelated entities.
Writing about mathematics is a guideline about writing mathematics-related articles. It is designed to ensure that all mathematics articles are well-written. A good article about a mathematical topic should follow this guideline. Each mathematics article should have an esoteric explanation. However, if possible, a mathematics article should ...
Technical writing is most commonly performed by a trained technical writer and the content they produce is the result of a well-defined process. Technical writers follow strict guidelines so the technical information they share appears in a single, popularly used and standardized format and style (e.g., DITA, markdown format, AP Stylebook, Chicago Manual of Style).
While a monkey is used as a mechanism for the thought experiment, it would be unlikely to ever write Hamlet, according to researchers.. The infinite monkey theorem states that a monkey hitting keys at random on a typewriter keyboard for an infinite amount of time will almost surely type any given text, including the complete works of William Shakespeare.
