  2. Wallis product - Wikipedia

    en.wikipedia.org/wiki/Wallis_product

    Wallis derived this infinite product using interpolation, though his method is not regarded as rigorous. A modern derivation can be found by examining ∫ 0 π sin n ⁡ x d x {\displaystyle \int _{0}^{\pi }\sin ^{n}x\,dx} for even and odd values of n {\displaystyle n} , and noting that for large n {\displaystyle n} , increasing n ...

    The sequence () is decreasing and has positive terms. In fact, for all : >, because it is an integral of a non-negative continuous function which is not identically zero; + = ⁡ + ⁡ = (⁡) (⁡) >, again because the last integral is of a non-negative continuous function.

  4. Integration by parts - Wikipedia

    en.wikipedia.org/wiki/Integration_by_parts

    Integration by parts is a heuristic rather than a purely mechanical process for solving integrals; given a single function to integrate, the typical strategy is to carefully separate this single function into a product of two functions u(x)v(x) such that the residual integral from the integration by parts formula is easier to evaluate than the ...

  5. Lists of integrals - Wikipedia

    en.wikipedia.org/wiki/Lists_of_integrals

    Integration is the basic operation in integral calculus.While differentiation has straightforward rules by which the derivative of a complicated function can be found by differentiating its simpler component functions, integration does not, so tables of known integrals are often useful.

  6. Template : Axler Measure, Integration & Real Analysis

    en.wikipedia.org/wiki/Template:Axler_Measure...

    This is a specific-source template for the textbook Measure, Integration & Real Analysis by Sheldon Axler.Transcluding specific-source templates rather than writing out citations reduces code duplication across articles and allows improvements — such as adding a zbMATH number or wikilinking the name of an author or editor — to apply to all uses of the source at once.

  7. John Wallis - Wikipedia

    en.wikipedia.org/wiki/John_Wallis

    Wallis' development of a model of English grammar, independent of earlier models based on Latin grammar, is a case in point of the way other sciences helped develop cryptology in his view. [37] Wallis tried to teach his own son John, and his grandson by his daughter Anne, William Blencowe the tricks of the trade.

  8. Functional integration - Wikipedia

    en.wikipedia.org/wiki/Functional_integration

    Functional integration is a collection of results in mathematics and physics where the domain of an integral is no longer a region of space, but a space of functions. Functional integrals arise in probability , in the study of partial differential equations , and in the path integral approach to the quantum mechanics of particles and fields.

  9. Common integrals in quantum field theory - Wikipedia

    en.wikipedia.org/wiki/Common_integrals_in...

    The angular integration of an exponential in cylindrical coordinates can be written in terms of Bessel functions of the first kind [4] [5]: 113 ⁡ (⁡ ()) = and ⁡ ⁡ (⁡ ()) = (). For applications of these integrals see Magnetic interaction between current loops in a simple plasma or electron gas .
