Expressing limits as definite integrals
WebJul 28, 2024 · 3 Answers Sorted by: 8 The goal is to represent the limit lim n → ∞ ∑ k = 1 n ( 1 + 2 k n) ⋅ 2 n as an integral. In fact, any integral like ∫ a b f ( x) d x can be approximated as a sum of n rectangles: ∫ a b f ( x) d x ≈ ∑ k = 1 n f ( a + k ⋅ Δ x) ⋅ Δ x WebApr 11, 2024 · Replace by (where is the antiderivative of ) in both integrals, integrate-by-parts in the second integral, and then compare it to the first. Ah yes, I think I see at least partly. If I write , then . goes to 0 at the lower limit if converges, but I am not quite sure how I can justify it going to zero at the upper limit.

WebDec 4, 2009 · The infinite sum is the integral, giving "exact" area as opposed to approximate. It is expressed as the limit of the summation as n goes to infinity, (what it would be if n really could go to infinity!). Evaluating an integral between "definite limits" uses the term "limit" in a new sense. These limits are the edges of the bounded area on …

WebDefinite integrals represent the exact area under a given curve, and Riemann sums are used to approximate those areas. However, if we take Riemann sums with infinite rectangles of infinitely small width (using limits), we get the exact area, i.e. the definite integral! Created by Sal Khan.
