If we could apply the dominated convergence theorem using 1 x as the bound, we would conclude that ∫ 1 ∞ 1 x = 0. Share Cite Follow answered May 2, 2015 at 22:50 Milo Brandt 59.6k 5 102 187 1

Nettet29. aug. 2011 · A google search said "Just use the substitution u = x+1, then replace dx with du and you get u+1/u = 1 + 1/u which you can integrate to give u + ln u, thus = x-1 + ln (x-1)". But I am pretty sure that you can't just add +1 to the numerator like that. I also know that it can be done using tables but is there a way not to use tables? Nettet5. jan. 2024 · So, x − 1 x3 + x = − 1 x + x + 1 x2 + 1. Therefore, ∫ (x − 1)dx x3 +x = ∫ −1dx x + ∫ (x + 1)dx x2 + 1. = ∫ −1dx x +∫ xdx x2 + 1 +∫ 1dx x2 + 1. We calculate each integral separately. −∫ dx x = −ln( ∣ x ∣) Let u = x2 + 1, ⇒, du = 2xdx. ∫ xdx x2 +1 = ∫ 2du u = 1 2lnu.
