Hi all, I just wanted to post and ask for help on a quiz question I had yesterday. The teacher generally does not explain and I'm a little lost. Online integration calculators also will not give help me because he asks for a specific u substitution which the calculator does not present as an option. The question is:
I get up to about when I'm substituting in u and du, because I find that du is an unwieldy fraction and I'm not sure what to do with the x3 in the top. According to the integration calculator I consulted, if u had just been (x2+1), then x3 would become (u-1) (which I'm also not sure about how but is not the pressing question).
Thank you for your time!
