bug in Integrate

  • To: mathgroup at
  • Subject: [mg74756] bug in Integrate

The following integral is evaluated wrong by Mathematica

f = HoldForm[Integrate[x*BesselJ[0, x]*Cos[x], {x, 0, Infinity}]]


The integral is divergent.

The same holds true for the following integral

g = HoldForm[Integrate[x*BesselJ[0, x]*Sin[x], {x, 0, Infinity}]]

Integrate::gener: Unable to check convergence.

but this time we get a warning message that indicates that the result
might be wrong; as it is.
