Indefinate integrals, erroneus Natural log?
Hi, In preparation for a major exam tomorrow, I was just checking some of my answers to past-papers with mathematica, I fed it this input: In:= \!\(\[Integral]\((xE\^\(2 x\))\) \[DifferentialD]x\) Out= \!\(xE\^\(2\ x\)\/\(2\ Log[xE]\)\) I marked myself wrong and moved on to the next question, but I happened accross the actual mark-scheme which said I was correct. It gave this answer: ((1/2)xE^(2x))-(1/4)e^(2x) My Integral calculus isn't so strong, so I don't know if the additional natural log should be there, or if the two expressions are identical. Thanks
