Antiderivative of x-1?

I admit, I'm a fucking brainlet, but what is the antiderivative of f(x)=1/x? I'm sure that I can find the answer in my textbook or on google, but I thought you guys could need some fuel for your superiority complexes, and I'm therefore asking you.

are you retarded?
it's log(x) this is literally precalc tier. Every fucking book on calculus has tables for the most common antiderivatives.

Proving it is something more complicated I guess.

lmgtfy.com/?q=antiderivative of 1/x

It was neither on the table of common derivatives nor in the index, hence I'm asking.

Kek nice one OP.
I'm starting to recognise your posts now.

it's actually quite easy to prove.

>proving it
>not defining it as such

>Brainlets thinking log(x) is the antiderivative of 1/x

You are but like children, 1/x is defined on all of R but log(x) is only defined on R+

did you just divide by 0

Did you just assume his autism?
