why is this the suggested solution? cant i just seperate the integral and substitute t=lnx?

It's not weird. Integral of 1 is x. Integral of (ln x)/x dx is (ln x) d(ln x), so at the end we get (ln x)^2/2

its hard that a student would think to integrate lnx/x as (lnx)^2/2 no?
like yeah looking at it it makes sense but i would never think of it

I think it depends on materials and teachers. I also think it is used a lot (from my own experience).

hm i see. to be honest, we are provided with an extremely basic integral table and we are left to figure out the rest ourselves
sometimes it works out sometimes it doesnt lmao
you gotta do what you gotta do 😄
