so basically we treat it as 1x lnx and integrate the 1 to x - nice

For those wondering: This is a caculus 2 method (or AP Calculus BC). I was originally confused as well lol

is 'v' really necessary then? if 'x' = 'v' then why not just state 'x' from the start

0:40 I still don't understand why we should pick dx for dv (dv=dx) instead of x for dv (dv=x) (since x is inside of ln)

If I differentiate the answer, I get "lnx — 1" instead of lnx
