WebSep 18, 2024 · Let us start with the first sum and then say you want a new summation index. k = i − 1. If you sum i from 2 to 19, that means you sum k from 1 = 2 − 1 to 18 = 19 − 1. And to see what happens to the summands, compute as follows, useing that k = i − 1, ∑ i = 2 … WebSummations are not like integrals. When you calculate an integral, swapping the boundaries does change the sign of the result. However, when talking about summations: ∑ n = − ∞ − 1 a ( n) = ∑ n = − 1 − ∞ a ( n) This holds because it is the same if we perform the sum of a ( − 1) + a ( − 2) +... + a ( − k) for any k > 0 in any order.
