Firstly the "integrator" tool at wolfram evaluates the indefinite integral. Fine Here are some examples of incorrect answers of the "integrator" INT means the integral sign INT 1 / x ln x Don't feel bad though I found another site at mss.vanderbilt.edu that got it wrong as well Now this is quite a fundamental integral but is it hopelessly botched by the "integrator." Here is another INT ln x the "integrator" got that wrong as well. I did find a site that got it right though. Where the error lies I don't know but do in fact think it may be somewhere in the original mathematica code. BTW can anyone on this list give me the correct answers to the above thanks geo.
