How do I integrate x(arctanx) dx? Is it some sort of integration by parts? Can you please show steps? Thanks in advance!

yes.

Let u = arctan(x)
du = dx/(x^2 + 1)

dv = x dx
v = x^2/2

That gets rid of the pesky trig stuff, and you're just left with a rational function, which brings back the arctan after integrating!
