  • Delivered-to:

A couple of colleagues wondered about this. I've sent it on to support @ wolfram who are escalating it to the developers. Possibly someone here has an answer though ?

Integrate[Cos[\[Beta]] Exp[I z Cos[\[Beta]-\[Alpha]]],{\[Beta],0,2 \[Pi]},Assumptions->z\[Element]Reals]

doesn't seem to run.

Answer should be

2 I \[Pi] BesselJ[1,z] Cos[\[Alpha]]  [ I think ]
