In mathematics, Euler–Boole summation is a method for summing alternating series. The concept is named after Leonhard Euler and George Boole. Boole published this summation method, using Euler's polynomials, but the method itself was likely already known to Euler. Euler's polynomials are defined by
The periodic Euler functions modify these by a sign change depending on the parity of the integer part of x {\displaystyle x} :
The Euler–Boole formula to sum alternating series is
where a , m , n ∈ N , a < n , h ∈ [ 0 , 1 ] {\displaystyle a,m,n\in \mathbb {N} ,a<n,h\in [0,1]} and f ( k ) {\displaystyle f^{(k)}} is the kth derivative.
