WebNov 16, 2024 · Notice that if we ignore the first term the remaining terms will also be a series that will start at n = 2 n = 2 instead of n = 1 n = 1 So, we can rewrite the original series as follows, ∞ ∑ n=1an = a1 + ∞ ∑ n=2an ∑ n = 1 ∞ a n = a 1 + ∑ n = 2 ∞ a n. In this example we say that we’ve stripped out the first term. WebSimplifying the double summation. Let’s simplify that double summation. Note that there are N 2 terms. We can write the N 2 different values of the denominator. as entries in an NxN matrix, where rows are indexed by m , columns by i .
