use integration by parts to find the integral of ln(x+1) dx
any help would be appreciated
Whoah! Careful now.
You could split
into
and have
which is fine.
But here's a short cut - notice that one integral of 1 is x + 1, and choose u = x+1 for du = 1.
I.e.
Picture shortly...
Don't integrate - balloontegrate!
