  2. Residue (complex analysis) - Wikipedia

    en.wikipedia.org/wiki/Residue_(complex_analysis)

    It may be that the function f can be expressed as a quotient of two functions, () = (), where g and h are holomorphic functions in a neighbourhood of c, with h(c) = 0 and h'(c) ≠ 0. In such a case, L'Hôpital's rule can be used to simplify the above formula to:

  3. Series acceleration - Wikipedia

    en.wikipedia.org/wiki/Series_acceleration

    Two classical techniques for series acceleration are Euler's transformation of series [1] and Kummer's transformation of series. [2] A variety of much more rapidly convergent and special-case tools have been developed in the 20th century, including Richardson extrapolation, introduced by Lewis Fry Richardson in the early 20th century but also known and used by Katahiro Takebe in 1722; the ...

    Let = = be an infinite sum whose value we wish to compute, and let = = be an infinite sum with comparable terms whose value is known. If the limit := exists, then is always also a sequence going to zero and the series given by the difference, = (), converges.

    AECOM (/ eɪ. iː ˈ k ɒ m /, ay-ee-KOM; formerly AECOM Technology Corporation; stylised AΞCOM) is an American multinational infrastructure consulting firm headquartered in Dallas, Texas. The company's official name from 1990–2015 was AECOM Technology Corporation, and is now AECOM. [ 2 ]

  6. List of limits - Wikipedia

    en.wikipedia.org/wiki/List_of_limits

    In general, any infinite series is the limit of its partial sums. For example, an analytic function is the limit of its Taylor series, within its radius of convergence. = =. This is known as the harmonic series. [6]

  7. Indeterminate form - Wikipedia

    en.wikipedia.org/wiki/Indeterminate_form

    Indeterminate form is a mathematical expression that can obtain any value depending on circumstances. In calculus, it is usually possible to compute the limit of the sum, difference, product, quotient or power of two functions by taking the corresponding combination of the separate limits of each respective function.

  8. Limit of a sequence - Wikipedia

    en.wikipedia.org/wiki/Limit_of_a_sequence

    Here, one can see that the sequence is converging to the limit 0 as n increases. In the real numbers , a number L {\displaystyle L} is the limit of the sequence ( x n ) {\displaystyle (x_{n})} , if the numbers in the sequence become closer and closer to L {\displaystyle L} , and not to any other number.

  9. Channel capacity - Wikipedia

    en.wikipedia.org/wiki/Channel_capacity

    When the SNR is large (SNR ≫ 0 dB), the capacity ⁡ ¯ is logarithmic in power and approximately linear in bandwidth. This is called the bandwidth-limited regime . When the SNR is small (SNR ≪ 0 dB), the capacity C ≈ P ¯ N 0 ln ⁡ 2 {\displaystyle C\approx {\frac {\bar {P}}{N_{0}\ln 2}}} is linear in power but insensitive to bandwidth.
