isn't the integrand function undefined at ?

Yes, there is a removable singularity at x=0.
If you want to do it more rigourously, you may treat the integrand as a piecewise continuous function.

In high school I thought these were too hard and I still think they're too hard LMAO

is this like a reverse chain + product rule integral or smth.

It's not my approach but you may try if it also works.

Spoiler

Judging from the upper and lower bounds, it may be a good idea to try the substitution u=1/x.

do u just randomly make integrals for your own satisfaction?

you don't?

Feel free to share your attempt.

I’m quite stuck with this question, been doing for week. Pretty appreciate your help

Hopefully I can introduce you another approach which is pure substitution and differential integration that I’m developing. However i need to prepare for trials atm!

Use the fact that for with equality holding for all x iff f(x) = 0.

 

[quickoats]

Note that so some of your working is incorrect.

I see I’ll check. Cuz i later figured out it’s Rolle theorem. Thank you, I’ll check them out

I see, yeah i just realized. Thank you, I’ll fix it

Looking forward to your approach.

i like how this is just a reskin of the BOS Trials' cancerous arctangent integral
