but that should result in -(1/y) isn't it ? and that wouldn't eliminate the L which is dividing GM (step 5), i have in those notes that the integrate should be something like [(Xp-L/2)-(Xp+L/2)]/(Xp-L/2)^2 is this correct ? or how should it be ?

In step 5, i don't know who the author goes from the integral to the result, i have some work from the classroom but i don't know if it is correct, my integration skills are somewhat rusty. Thanks, I'm glad to find a place to solve my doubt

A fixed number, thank you i can live with that, but i wasn't referring to the meaning of integration but to which method i can use, i cannot get to the same result, again thank you very much (if i have to go to the mathematics section, I am sorry, its my first day).
