Nasty bug in Integrate (version 5.0)

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]
