  2. Bailey–Borwein–Plouffe formula - Wikipedia

    en.wikipedia.org/wiki/Bailey–Borwein–Plouffe...

    Using the P function mentioned above, the simplest known formula for π is for s = 1, but m > 1. Many now-discovered formulae are known for b as an exponent of 2 or 3 and m as an exponent of 2 or it some other factor-rich value, but where several of the terms of sequence A are zero.

  3. Pi is 3 - Wikipedia

    en.wikipedia.org/wiki/Pi_is_3

    Pi is 3 is a misunderstanding that the Japanese public believed that, due to the revision of the Japanese Curriculum guideline in 2002, the approximate value of pi (π), which had previously been taught as 3.14, is now taught as 3 in arithmetic education.

  4. List of sums of reciprocals - Wikipedia

    en.wikipedia.org/wiki/List_of_sums_of_reciprocals

    The sum of the reciprocals of the pentatope numbers is ⁠ 4 / 3 ⁠ . Sylvester's sequence is an integer sequence in which each member of the sequence is the product of the previous members, plus one. The first few terms of the sequence are 2, 3, 7, 43, 1807 . The sum of the reciprocals of the numbers in Sylvester's sequence is 1.

  5. Prime-counting function - Wikipedia

    en.wikipedia.org/wiki/Prime-counting_function

    For x > 1 let π 0 (x) = π(x) − ⁠ 1 / 2 ⁠ when x is a prime number, and π 0 (x) = π(x) otherwise. Bernhard Riemann, in his work On the Number of Primes Less Than a Given Magnitude, proved that π 0 (x) is equal to [9] Riemann's explicit formula using the first 200 non-trivial zeros of the zeta function

  6. Supergolden ratio - Wikipedia

    en.wikipedia.org/wiki/Supergolden_ratio

    Its true value is the real solution of the equation x 3 = x 2 + 1. The name supergolden ratio results from analogy with the golden ratio, the positive solution of the equation x 2 = x + 1. A triangle with side lengths ψ, 1, and 1 ∕ ψ has an angle of exactly 120 degrees. [1]

  7. Holtsmark distribution - Wikipedia

    en.wikipedia.org/wiki/Holtsmark_distribution

    The Holtsmark distribution is a special case of a stable distribution with the index of stability or shape parameter equal to 3/2 and the skewness parameter of zero. Since β {\displaystyle \beta } equals zero, the distribution is symmetric, and thus an example of a symmetric alpha-stable distribution.

  8. Linear canonical transformation - Wikipedia

    en.wikipedia.org/wiki/Linear_canonical...

    In Hamiltonian mechanics, the linear canonical transformation (LCT) is a family of integral transforms that generalizes many classical transforms. It has 4 parameters and 1 constraint, so it is a 3-dimensional family, and can be visualized as the action of the special linear group SL 2 (C) on the time–frequency plane (domain).
