Yes, integration by parts will make this easier, we have
and as for the computation for last integral we have and put to finish the problem.
\int \frac{xtan^-1 } {sqrt 1+x^2} dx
I'm pretty sure I have to find uv, v, du and u, but I'm having some trouble with it. Tried trigonometric substitution but it doesn't seem to be working. any help would be appreciated
hope the problem's understandable
