Hi, Sorry if this has been discussed before. Could anyone explain why Mathematica 5.0 is ignoring the term 1/x in the first and second answers? Thanks! In[1]:= Integrate[1/x + x^c, {x, a, b}] Out[1]= (-a^(1 + c) + b^(1 + c))/(1 + c) In[2]:= Integrate[1/x + x^c, {x, a, b}, Assumptions -> {Element[a, Reals], Element[b, Reals]}] Out[2]= (-a^(1 + c) + b^(1 + c))/(1 + c) In[3]:= Integrate[1/x + x^c, {x, a, b}, Assumptions -> {a > 0, b > 0}] Out[3]= (-a^(1 + c) + b^(1 + c))/(1 + c) + Log[b/a]
