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}

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 J V Grabiner, A mathematician among the molasses barrels : Maclaurin's unpublished memoir on volumes.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.
