tutorinseoul Posted March 23, 2017 Report Share Posted March 23, 2017 I like this question a lot as it goes over an intense substitution. Overall, standard question for paper 3 option 9 :)! Enjoy! 1 Reply Link to post Share on other sites More sharing options...
SC2Player Posted March 25, 2017 Report Share Posted March 25, 2017 My answer's in the attached file. First time doing improper integrals, so a bit annoying, but finally got the answer woo. I'm not too sure how parts a) and b) are linked though. Other answer.pdf Reply Link to post Share on other sites More sharing options...

Other answer.pdf I think the question is saying how equivalent expressions can change the difficulty of evaluating the integrand. For example if we substitute part a) into b), then integral becomes much more difficult, with an hairy denominator. Part a) shows how that hard integral can be simplified to b).
