  2. Formula for primes - Wikipedia

    en.wikipedia.org/wiki/Formula_for_primes

    In number theory, a formula for primes is a formula generating the prime numbers, exactly and without exception. Formulas for calculating primes do exist; however, they are computationally very slow. Formulas for calculating primes do exist; however, they are computationally very slow.

  3. Arithmetic progression - Wikipedia

    en.wikipedia.org/wiki/Arithmetic_progression

    Proof without words of the arithmetic progression formulas using a rotated copy of the blocks.. An arithmetic progression or arithmetic sequence is a sequence of numbers such that the difference from any succeeding term to its preceding term remains constant throughout the sequence.

  4. Recurrence relation - Wikipedia

    en.wikipedia.org/wiki/Recurrence_relation

    In mathematics, a recurrence relation is an equation according to which the th term of a sequence of numbers is equal to some combination of the previous terms. Often, only previous terms of the sequence appear in the equation, for a parameter that is independent of ; this number is called the order of the relation.

  5. Cauchy formula for repeated integration - Wikipedia

    en.wikipedia.org/wiki/Cauchy_formula_for...

    The Cauchy formula for repeated integration, named after Augustin-Louis Cauchy, allows one to compress n antiderivatives of a function into a single integral (cf. Cauchy's formula). For non-integer n it yields the definition of fractional integrals and (with n < 0) fractional derivatives.

  6. Integration by parts - Wikipedia

    en.wikipedia.org/wiki/Integration_by_parts

    The essential process of the above formula can be summarized in a table; the resulting method is called "tabular integration" [5] and was featured in the film Stand and Deliver (1988). [ 6 ] For example, consider the integral

  7. Iterated function - Wikipedia

    en.wikipedia.org/wiki/Iterated_function

    One of several methods of finding a series formula for fractional iteration, making use of a fixed point, is as follows. [15] First determine a fixed point for the function such that f(a) = a. Define f n (a) = a for all n belonging to the reals. This, in some ways, is the most natural extra condition to place upon the fractional iterates.

  8. Tetration - Wikipedia

    en.wikipedia.org/wiki/Tetration

    Exponentiating the next leftward a (call this the 'next base' b), is to work leftward after obtaining the new value b^c. Working to the left, use the next a to the left, as the base b, and evaluate the new b^c. 'Descend down the tower' in turn, with the new value for c on the next downward step.

  9. Bernoulli number - Wikipedia

    en.wikipedia.org/wiki/Bernoulli_number

    In mathematics, the Bernoulli numbers B n are a sequence of rational numbers which occur frequently in analysis.The Bernoulli numbers appear in (and can be defined by) the Taylor series expansions of the tangent and hyperbolic tangent functions, in Faulhaber's formula for the sum of m-th powers of the first n positive integers, in the Euler–Maclaurin formula, and in expressions for certain ...
