## Main Question or Discussion Point

Does anyone know whether the following integral has a closed-form solution? If not, is anything known about the asymptotic behavior?

[itex]f(x) = \int_{-\infty}^{+\infty} \frac{e^{iux}}{\sqrt{u^2 + 1}} du[/itex]

[itex]f(x) = \int_{-\infty}^{+\infty} \frac{e^{iux}}{\sqrt{u^2 + 1}} du[/itex]
