To the Group, In[104]:= LaplaceTransform[D[f[t],t],t,s] Out[104]= -f[0] + s LaplaceTransform[f[t],t,s] In[105]:= LaplaceTransform[Integrate[f[t],t],t,s] Out[105]= LaplaceTransform[Integrate[f[t] ,t], t, s] Item 104 is correct, but item 105 is not. The correct 105 should be: -f[0]/s + LaplaceTransform[f[t],t,s]/s . If Mathematica can get 104 right, then it should also produce a correct 105. This looks like a bug. Any thoughts on this? (Note: Number 105 does not look like that on the notebook page. It shows the indefinite integral with an integral symbol followed by f[t] dt instead of the function Integrate[ ]. I've spelled it out because the e-mail won't show the symbol.) Thanks, Raul Martinez Vista Research, Inc.
