Unexpected message 2


I forgot to mention that even settings like the following have no
results

In[19]:=
Integrate[Cos[a*x]*CosIntegral[b*x], {x, 0, Infinity}, Assumptions ->
a > b > 0]
Integrate::idiv: Integral of Cos[a\x]\CosIntegral[b\x] does not
converge on \
{0, =E2=88=9E}.
Out[19]=
Integrate[Cos[a*x]*CosIntegral[b*x], {x, 0, Infinity}, Assumptions ->
a > b > 0]

In[20]:=
Integrate[Cos[a*x]*CosIntegral[a*x], {x, 0, Infinity}]
Integrate::idiv: Integral of Cos[a\x]\CosIntegral[a\x] does not
converge on \
{0, =E2=88=9E}.
Out[20]=
Integrate[Cos[a*x]*CosIntegral[a*x], {x, 0, Infinity}]

Note also that e.g.

In[70]:=
Integrate[Cos[EulerGamma*x]*CosIntegral[b*x], {x, 0, Infinity}]
Integrate::idiv: Integral of Cos[EulerGamma\x]\CosIntegral[b\x] does
not \
converge on {0, =E2=88=9E}.
Out[70]=
Integrate[Cos[EulerGamma*x]*CosIntegral[b*x], {x, 0, Infinity}]

In[72]:=
Integrate[Cos[a*x]*CosIntegral[EulerGamma*x], {x, 0, Infinity}]
Integrate::idiv: Integral of Cos[a\x]\CosIntegral[EulerGamma\x] does
not \
converge on {0, =E2=88=9E}.
Out[72]=
Integrate[Cos[a*x]*CosIntegral[EulerGamma*x], {x, 0, Infinity}]
