Homework Equations
The Attempt at a Solution
I am stuck on this question because i really have no idea what should i be doing here with sin(1/x) and cos(1/x). I do not know how to integrate them. Even if i try to integrate by parts, i am stuck with these sin(1/x) and cos(1/x).
Any help is appreciated.
Thanks!
