break it up into two integral (ln(x)) and x(ln(x)) for the second part do a u substitution where u = ln(x); du = dx/x

yes, use dv=1x and u=ln(x)

no we cannot give direct answers here, why don't you try and show us how you do?

its pretty long. but my answer is ln x [ x  (x^2/2) ]  x  (x^2/4) + C

tomo Group TitleBest ResponseYou've already chosen the best response.0
yeah, u sub wouldn't work since u = ln(x), du = dx/x , x*du = dx.

but that answer is correct :)

oh I think except for a minus sign... ln x [ x  (x^2/2) ]  x + (x^2/4) + C
