    Someone pliz can you solve this integral with the steps..

    xln(x+(1+(1+x^2)^1/2)/(1-x^2)^2

    the answer is... ln(x+(1+x^2)^1/2)/2(1-x^2) + 1/4(2)^1/2ln(((1+x^2)-x(2)^1/2)/ ((1+x^2)^1/2+x(2)^1/2))

    but how do i get this answer?
    please a ineed the steps

    Which integral are you solving now? For the former, it'll help a lot if you typed it out in Latex. Is it supposed to be like this:
    [tex]\int x ln \left| x + \frac{1+\sqrt{1+x^2}}{(1-x^2)^2} \right | dx[/tex]

    I got to this point


    1/(Sqrt[1+x^2](1-x^2))
