I have a problem in calculating this integral shown below(I've posted this question before, but I typed Exp[-x] as Exp[x] incorrectly so you have figured out both of them were not converge): Integrate[Log[1+Exp[-x]/Sqrt[x]],{x,0,Infinity}] Pi^2/6 N[%] 1.64493 NIntegrate[Log[1+Exp[-x]/Sqrt[x]],{x,0,Infinity}] 1.01799 Where does this difference come from and which one is correct?
