I have tried several times to perform an integration(math..2.2.3)B similar to the following. In[1]:=Integrate[(ao+x)^-1 (bo^-2), x] The results, however, are always incorrect: Out[1]=-ln(-ao+x) <---where the constant "ao" should be positive. Note: The above is not the exact problem and solution. It is only an example of the type of problem I have been having with the program. I have tried to specify the value of "ao" before integrating: In[1]:=SetAttribute[ao, Constant] or In[1]:=SetAttribute[ao, Protected] or a combination of the two. I have also tried: In[1]:=ao/. Sign[ao]=1 To try and get a positive result. I have also tried MathCad 6.0+ and gotten the same results. It appears to be a problem for both programs. (For those that might think that I am the one with the problem, I would like to say that a tenured prof and a postdoc agreed that there is a problem with the program). If you know of a solution, or can point me in a different direction, I would greatly appreciate it. This would save me from having to contact Wolfram about his program. -- ---------------------------------- -Dennis M. Winters - -P.O.
