  2. Hermite polynomials - Wikipedia

    en.wikipedia.org/wiki/Hermite_polynomials

    Like the other classical orthogonal polynomials, the Hermite polynomials can be defined from several different starting points.Noting from the outset that there are two different standardizations in common use, one convenient method is as follows:

  3. Standard form - Wikipedia

    en.wikipedia.org/wiki/Standard_form

    Standard form may refer to a way of writing very large or very small numbers by comparing the powers of ten. It is also known as Scientific notation. Numbers in standard form are written in this format: a×10 n Where a is a number 1 ≤ a < 10 and n is an integer. ln mathematics and science. Standard Form (SF) is the name of a set of forms used ...

  4. Vieta jumping - Wikipedia

    en.wikipedia.org/wiki/Vieta_jumping

    Replace some a i by a variable x in the formulas, and obtain an equation for which a i is a solution. Using Vieta's formulas, show that this implies the existence of a smaller solution, hence a contradiction. Example. Problem #6 at IMO 1988: Let a and b be positive integers such that ab + 1 divides a 2 + b 2. Prove that ⁠ a 2 + b 2 / ab + 1 ...

  5. Fibonacci sequence - Wikipedia

    en.wikipedia.org/wiki/Fibonacci_sequence

    With the exceptions of 1, 8 and 144 (F 1 = F 2, F 6 and F 12) every Fibonacci number has a prime factor that is not a factor of any smaller Fibonacci number (Carmichael's theorem). [58] As a result, 8 and 144 (F 6 and F 12) are the only Fibonacci numbers that are the product of other Fibonacci numbers. [59]

  6. Logarithm - Wikipedia

    en.wikipedia.org/wiki/Logarithm

    For example, a 5.0 earthquake releases 32 times (10 1.5) and a 6.0 releases 1000 times (10 3) the energy of a 4.0. [61] Apparent magnitude measures the brightness of stars logarithmically. [62] In chemistry the negative of the decimal logarithm, the decimal cologarithm, is indicated by the letter p. [63]

  7. Compressed sensing - Wikipedia

    en.wikipedia.org/wiki/Compressed_sensing

    The least-squares solution to such problems is to minimize the norm—that is, minimize the amount of energy in the system. This is usually simple mathematically (involving only a matrix multiplication by the pseudo-inverse of the basis sampled in). However, this leads to poor results for many practical applications, for which the unknown ...

    This /ɪu/ would become /juː/ in standard varieties of English, and later still /uː/ in some cases through "Yod-dropping". /iu/ remains in Welsh English and some other non-standard varieties. /ɔi/ and /ui/ merge to / o i̯ / (today / ɔɪ /), the only Middle English diphthong that remains in the modern standard English varieties.
