Calming

There is nothing more calming that working out few problems. I was looking at this problem that appeared in the recent Pi-Mu journal. Find the int(ln(1+x)/x,x,0,1). One easy way to solve this is using the series of ln(1+x)/x and then you end up with an alternating series which closely resembles bessel problem and then its easy to see that the even terms sum to bessel function.
