I don't consider a solution that includes
Si, Ci, or hypergeometric functions as a solution
in closed form in terms of elementary functions.

Unless there is no way of expressing the answer in
terms of elementary functions.

After all, you could always decide that the
difficult integral in question deserves its own
name, say FooI, and then return the answer in terms
of FooI.
