  2. Limit of a function - Wikipedia

    en.wikipedia.org/wiki/Limit_of_a_function

    e. In mathematics, the limit of a function is a fundamental concept in calculus and analysis concerning the behavior of that function near a particular input which may or may not be in the domain of the function. Formal definitions, first devised in the early 19th century, are given below.

  3. Limit inferior and limit superior - Wikipedia

    en.wikipedia.org/wiki/Limit_inferior_and_limit...

    In this case, the sequence accumulatesaround the two limits. The superior limit is the larger of the two, and the inferior limit is the smaller. The inferior and superior limits agree if and only ifthe sequence is convergent(i.e., when there is a single limit). The limit inferior of a sequence (xn){\displaystyle (x_{n})}is denoted bylim infn→ ...

  4. Limit (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Limit_(mathematics)

    In mathematics, a limit is the value that a function (or sequence) approaches as the input (or index) approaches some value. [1] Limits are essential to calculus and mathematical analysis, and are used to define continuity, derivatives, and integrals . In formulas, a limit of a function is usually written as.

    Mathematics portal. v. t. e. In mathematics, mathematical physics and the theory of stochastic processes, a harmonic function is a twice continuously differentiable function where U is an open subset of ⁠ ⁠ that satisfies Laplace's equation, that is, everywhere on U. This is usually written as or.

  7. Central limit theorem - Wikipedia

    en.wikipedia.org/wiki/Central_limit_theorem

    In probability theory, the central limit theorem ( CLT) states that, under appropriate conditions, the distribution of a normalized version of the sample mean converges to a standard normal distribution. This holds even if the original variables themselves are not normally distributed. There are several versions of the CLT, each applying in the ...

  8. Big O notation - Wikipedia

    en.wikipedia.org/wiki/Big_O_notation

    Big O notation is a mathematical notation that describes the limiting behavior of a function when the argument tends towards a particular value or infinity. Big O is a member of a family of notations invented by German mathematicians Paul Bachmann, [1] Edmund Landau, [2] and others, collectively called Bachmann–Landau notation or asymptotic ...

  9. List of prime numbers - Wikipedia

    en.wikipedia.org/wiki/List_of_prime_numbers

    Also called primes congruent to d modulo a . The primes of the form 2 n +1 are the odd primes, including all primes other than 2. Some sequences have alternate names: 4 n +1 are Pythagorean primes, 4 n +3 are the integer Gaussian primes, and 6 n +5 are the Eisenstein primes (with 2 omitted).
