Can you explain why they look similar to you? It's difficult to guess. – rschwieb Sep 13 '12 at 16:54

You can replace summation with integration using a suitable measure. :) – Hagen von Eitzen Sep 13 '12 at 16:55
Summation is integration with the counting measure. And integration (at least the most popular methods) is just the limit of sums... – copper.hat Sep 13 '12 at 16:56

Your question is too vague. Can you give an example of a situation in which you cannot choose between summation and integration? – copper.hat Sep 13 '12 at 17:15
