not really,but it kind of looks like a set up for integrating by parts

F'(x)=f(x) so we can say F'(t)=f(t) right..

that is what i was thinking, yes

maybe not exactly what you want, but you would get something like \(gF\int f g'\)

\[\lim_{b \rightarrow} \int\limits_{0}^{b }G(t)F'(t)dt=\]

I guess enough to show that \[\int\limits f g'\] is convergent

satellite73Best ResponseYou've already chosen the best response.1
first part is no problem, since \(\lim_{t\to \infty}g(t)=0\) and \(\int_a^\infty f(t)\) is bounded

yeah you hit the nail on the head, and frankly i don't see why that is true, so this might be the wrong approach

satellite73Best ResponseYou've already chosen the best response.1
because all you know about \(g'\) is that \(g'\leq 0\)

satellite73Best ResponseYou've already chosen the best response.1
does this come in a section after some theorem or lemma that maybe you are supposed to use?

no, this is homework, but prof gave the hint and said that you should use integration by part..

satellite73Best ResponseYou've already chosen the best response.1
well then i guess this is the right approach!
