I posted a message recently (Integration...Constants) that received several valuable responses requesting more information. Well, here is the actual problem: In[1]:=Integrate[(-2 x+ao)^-2 (-x+bo)^-1, x] Mathematica gives the following output: Out[1]=-(1/((ao-2 bo)(ao- 2 x))) - (Log(-bo+x)/(ao^2 - 4 ao bo + 4 bo^2)) + Log(-ao + 2 x)/(ao^2 - 4 ao bo + 4 bo^2) This answer is incorrect. If performed by hand, the answer is shown to have positive values for ao and bo. This is confirmed by the fact that this integration is a classical result of chemistry. Years of chemical reaction rate analysis show the values to be positive. Again, this calculation was performed using the unix version of 2.2.3. Any help from those who have already responded would be most appreciated. -- ---------------------------------- -Dennis M. Winters - -P.O.
