Webb9 feb. 2007 · The summations aren't from 1 to infinity (as they are in a power series), they're from 1 to n. For b), you could start by splitting it up into 2 sums: Note that the second sum on the RHS only needs to start at 1, not 0. As for the second sum, it's geometric, which makes the sum easy to find. WebbTools. In mathematics, summation by parts transforms the summation of products of sequences into other summations, often simplifying the computation or (especially) estimation of certain types of sums. It is also called Abel's lemma or Abel transformation, named after Niels Henrik Abel who introduced it in 1826. [1]
