  2. Limit (mathematics) - Wikipedia

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

    As x becomes extremely large, the value of f(x) approaches 2, and the value of f(x) can be made as close to 2 as one could wish—by making x sufficiently large. So in this case, the limit of f ( x ) as x approaches infinity is 2 , or in mathematical notation, lim x → ∞ 2 x − 1 x = 2. {\displaystyle \lim _{x\to \infty }{\frac {2x-1}{x}}=2.}

  3. Limit of a function - Wikipedia

    In his 1821 book Cours d'analyse, Augustin-Louis Cauchy discussed variable quantities, infinitesimals and limits, and defined continuity of = by saying that an infinitesimal change in x necessarily produces an infinitesimal change in y, while Grabiner claims that he used a rigorous epsilon-delta definition in proofs. [2]

  4. Limit inferior and limit superior - Wikipedia

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

    In mathematical analysis, limit superior and limit inferior are important tools for studying sequences of real numbers.Since the supremum and infimum of an unbounded set of real numbers may not exist (the reals are not a complete lattice), it is convenient to consider sequences in the affinely extended real number system: we add the positive and negative infinities to the real line to give the ...

  6. Central limit theorem - Wikipedia

    en.wikipedia.org/wiki/Central_limit_theorem

    Here one can say that the difference between the function and its approximation grows approximately as a 2 φ 2 (n). The idea is that dividing the function by appropriate normalizing functions, and looking at the limiting behavior of the result, can tell us much about the limiting behavior of the original function itself.

  7. Cauchy–Hadamard theorem - Wikipedia

    It was published in 1821 by Cauchy, [1] but remained relatively unknown until Hadamard rediscovered it. [2] Hadamard's first publication of this result was in 1888; [ 3 ] he also included it as part of his 1892 Ph.D. thesis.
