By using the substitution rule, one can adapt this formula also to functions "ƒ" which are defined on some other interval of the real line. Often the expansion remains valid even after taking the limits {scriptstyle a o -infty} or {scriptstyle b o +infty}, or both. }+\frac{x^{4}}{4 ! In order to get bounds on the size of the error when the sum is approximated by the integral, we note that the Bernoulli polynomials on the interval [0, 1] attain their maximum absolute values at the endpoints (see D.H. Lehmer in References below), and the value "B""n"(1) is the "n"th Bernoulli number. contenant 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". 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. The values "B""n"(1) are the Bernoulli numbers.

In this way we get a proof of the Euler–Maclaurin summation formula by mathematical induction, in which the induction step relies on integration by parts and on the identities for periodic Bernoulli functions.
