A couple of Integration problems 9dx/(x(x^4 + 8 )) 1. The problem statement, all variables and given/known data Hi I'm new to this forum. I have a couple of Integration Problems which im not able to integrate correctly. I will also post my attempt at solving the problem so u guys can see what method i took trying to solve these. spent a lot of time in these questions and finally decided to post in this forum. 1 9dx/(x(x^4 + 8 )) 2 integ 37dx/((root(x)+ xroot(x)) 3. The attempt at a solution My attempt i tried u substitution with u=x^2 also 9 is a constant so i took it out for the time being(ill multiply the answer i get with 9) 9 integ dx/(x(x^4 + 8 )) u = x^2 du=2xdx 9 integ xdx/(x^2(x^4 + 8 )) 9*1/2 integ du/(u(u^2 + 8 ) 9*1/2 integ du/(u^3 + 8u ) ?? 9*1/2 (ln|u^3 +8u|) <<is that answer correct? if not can someone kindly tell me how to do this problem pls. I do not know how to go about the 2nd problem. any hints on how to approach it are welcome :) thanks in advance!
