Homework Statement


Here's a screenshot of the solved integral by wolfram: http://puu.sh/4CIzy.png

The Attempt at a Solution



I get stuck about halfway through working through this, with ∫ln(2+y)-ln(1+y) dy [0,1]
My problem is I'm not sure how to integrate ln(2+y) or ln(1+y), since integration by parts doesn't seem to work for either of them, and if I had integrated in terms of y first I'd be left with similar, hard to integrate natural logs for x. Can someone walk me through how to integrate these?
