But beware: "The Answer" is only defined up to a constant, as wou wrote,andequivalence transformations of the entire term. It is sometimes not at all obvious at first glance that two such terms are, indeed, equivalent up to a constant...

This is ok.If anyone has some time then I would really appreciate the help.

NOTE: The step I got to and think I am right is:

This is just after i finished making the integral into partial fractions. Also if you were wondering what I used as my substitution.

So where, exactly, is your problem? As to the first integral:So ya I got a little stuck here. I have tried finding the integrals seperately although I can't seem to get it to work and it is hard to see where my errors are because the integrals are all seperate and I can't know if even 1 is right. My work so far may also be wrong too though

Thanks in advance for your help,

Luke

As to the second: a simple substitution like will do. And as to the third, I would apply a single step of partial integration to get an u into the numerator. Once you have that you can, again, apply the substitution .

But please: Consider first the possibility that your solution is really, if looked at closely enough,equivalentto "The Answer" that your book gives - up to a constant.
