BOGGUS'S COOL SITE WebMar 29, 2024 · To evaluate. lim n → ∞ ∑ k = 1 n k 2 + n 2 n 3 + 1. by the method of Riemann sums, note that we need to express the sum as an average, so we will divide by n, which means we will want Δ x to equal 1 / n. Unfortunately, we have n 3 + 1 in the denominator, but we can replace it by n 3, since. lim n → ∞ n 3 n 3 + 1 = 1.
