Abstract: This paper provides id an estimation method for the sum n/Σ/n=0(-l)n.f(n). It results in the method for crisscross series. Compared with the usual method (1), it is more accurate and also simpler than Euler- Maclaurin's Sum Formula.

Key words: estimation; integration by parts; infinite integration
