    en.wikipedia.org/wiki/Period_(algebraic_geometry)

    The algebraic periods as a subset of the complex numbers. In mathematics, specifically algebraic geometry, a period or algebraic period[1] is a complex number that can be expressed as an integral of an algebraic function over an algebraic domain. The periods are a class of numbers which includes, alongside the algebraic numbers, many well known ...

  3. Periodic function - Wikipedia

    en.wikipedia.org/wiki/Periodic_function

    Periodic function. A periodic function also called a periodic waveform (or simply periodic wave), is a function that repeats its values at regular intervals or periods. The repeatable part of the function or waveform is called a cycle. [1] For example, the trigonometric functions, which repeat at intervals of radians, are periodic functions.

    en.wikipedia.org/wiki/Periodic_sequence

    A (purely) periodic sequence (with period p), or a p-periodic sequence, is a sequence a 1, a 2, a 3, ... satisfying . a n+p = a n. for all values of n. [1] [2] [3] If a sequence is regarded as a function whose domain is the set of natural numbers, then a periodic sequence is simply a special type of periodic function.

  5. Repeating decimal - Wikipedia

    The period of ⁠ 1 / p 2 ⁠ is usually pT p, where T p is the period of ⁠ 1 / p ⁠. There are three known primes for which this is not true, and for those the period of ⁠ 1 / p 2 ⁠ is the same as the period of ⁠ 1 / p ⁠ because p 2 divides 10 p−1 −1. These three primes are 3, 487, and 56598313 (sequence A045616 in the OEIS). [12]

  6. Fibonacci sequence - Wikipedia

    en.wikipedia.org/wiki/Fibonacci_sequence

    In mathematics, the Fibonacci sequence is a sequence in which each number is the sum of the two preceding ones. Numbers that are part of the Fibonacci sequence are known as Fibonacci numbers, commonly denoted Fn . Many writers begin the sequence with 0 and 1, although some authors start it from 1 and 1 [1][2] and some (as did Fibonacci) from 1 ...

  8. Numerical digit - Wikipedia

    en.wikipedia.org/wiki/Numerical_digit

    A numerical digit (often shortened to just digit) or numeral is a single symbol used alone (such as "1") or in combinations (such as "15"), to represent numbers in a positional numeral system. The name "digit" comes from the fact that the ten digits (Latin digiti meaning fingers) [1] of the hands correspond to the ten symbols of the common base ...
