La… …   Wikipedia Español, Formule d'Euler-Maclaurin — En mathématiques, la formule d Euler Maclaurin (appelée parfois formule sommatoire d Euler) est une relation entre sommes discrètes et intégrales. It was discovered independently by Euler and Maclaurin and published by Euler in 1732, and by Maclaurin in 1742. The Euler–Maclaurin formula provides expressions for the difference between the sum and the integral in terms of the higher derivatives "ƒ"("k") at the end points of the interval 0 and "n". ${f}”(0)=e^{0}=1$ If "n" is a natural number and "f"("x") is a smooth (meaning: sufficiently often differentiable) function defined for all real numbers "x" between 0 and "n", then the integral, can be approximated by the sum (or vice versa), :S=frac{1}{2}f(0)+fleft( 1 ight) +cdots+fleft( n-1 ight) +frac{1}{2}f(n), (see trapezoidal rule). For instance, if "f"("x") = "x"3, we can choose "p" = 2 to obtain after simplification, :sum_{i=0}^n i^3=left(frac{n(n+1)}{2} ight)^2.

It is a special case of Taylor series when x = 0. x k et le reste de Maclaurin est R (n,f) (x)=f (x)-T (n,f) (x). nous obtenons la formule de Mac Laurin : Déterminer le développement limité de Mac Laurin de la fonction, Déterminer le développement limité du polynôme, Formule de Taylor. end{align}, Adding ("ƒ"(0) + "ƒ"("n"))/2 to both sides and rearranging, we have, : sum_{k=0}^n f(k) = int_0^n f(x),dx + {f(0) + f(n) over 2} + int_0^n f'(x) P_1(x),dx.qquad (1). In the context of computing asymptotic expansions of sums and series, usually the most useful form of the Euler–Maclaurin formula is. J V Grabiner, A mathematician among the molasses barrels : Maclaurin's unpublished memoir on volumes. The above is a formal notation for the idea of taking derivatives at a point; thus one has, :int_0^1 ilde{B}_n(x) f(x), dx = frac{1}{n!} I�χ��x,�i�*A�� %���� The expansion in terms of the Bernoulli polynomials has a non-trivial kernel. Hist. Proof: The proof proceeds along the lines of the Abel partial summation formula. This results in an asymptotic expansion for {scriptstyle psi^{(1)}(z)}. That expansion, in turn, serves as the starting point for one of the derivations of precise error estimates for Stirling's approximation of the factorial function. We follow the argument given in (Apostol) [Tom M. Apostol, "An Elementary View of Euler's Summation Formula", "American Mathematical Monthly", volume 106, number 5, pages 409—418 (May 1999).

Explicitly, for any natural number "p", we have, :S-I= sum_{k=2}^pfrac{B_{k{k! : P_n(0) = P_n(1)= B_nquad ext{for } n>1. London 38 (2) (1984), 235-240.

Then all the terms in the asymptotic series can be expressed in terms of elementary functions. Euler computed this sum to 20 decimal places with only a few terms of the Euler–Maclaurin formula in 1735. The Bernoulli polynomials, along with their duals, form an orthogonal set of states on the unit interval: one has, :int_0^1 ilde{B}_m(x) B_n(x), dx = delta_{mn}. :left|R ight|leqfrac{2}{(2pi)^{2(p+1)int_0^nleft|f^{(p)}(x) ight|,dx. Free Maclaurin Series calculator - Find the Maclaurin series representation of functions step-by-step. The Bernoulli polynomials "B""n"("x"), "n" = 0, 1, 2, ... are defined recursively as. \end{align}, :egin{align}int_k^{k+1} f(x),dx &= uv - int v,du &{}\&= Big [f(x)P_1(x) Big] _k^{k+1} - int_k^{k+1} f'(x)P_1(x),dx \ \&=-B_1(f(k) + f(k+1)) - int_k^{k+1} f'(x)P_1(x),dx.end{align}, Summing the above from "k" = 0 to "k" = "n" − 1, we get, :egin{align}&int_0^{1} f(x),dx+dotsb+int_{n-1}^{n} f(x),dx \&= int_0^n f(x), dx \&= frac{f(0)}{2}+ f(1) + dotsb + f(n-1) + {f(n) over 2} - int_1^n f'(x) P_1(x),dx. }left(f^{(k-1)}(n)-f^{(k-1)}(0) ight)+R.end{align}. Then value "x" = 0 and rearranging terms, one obtains an expression for "f(0)". Soc. + R n 2. définie et continue au voisinage de Learn more Accept.
