Corrected summation of alternating series

Judith Gal-Ezer, Gideon Zwas

Research output: Contribution to journalArticlepeer-review


This article treats the summation of alternating infinite series, whose terms decrease to zero, and in addition satisfy certain 'convexity conditions’. Corrected partial sums are constructed, without any use of calculus, so as to accelerate the summation of the series. That is, the number of terms needed to achieve a desired accuracy, is significantly reduced. Examples and counter examples are given to demonstrate to the students the usefulness of the corrected summation. The introduction of these corrected sums well suits the teaching of infinite series, while emphasizing the difference between theoretical convergence and actual summation.
