I came to this integral which I thaught would be easy to solve, but I'm stuck.

int dx/{x *sqrt{(x ^ 2 )+ k}}

(Sorry Im trying to get it in Latex)

I tried substitution:

[tex]x ^ 2 + k = t[/tex]

as I remembered from the book (years ago)

But have ended with this:

1/2 times

int dt/{(t-k)sqrt(t)}

Im not sure if this leads to a solution. Any help would be appreciated
