I recently came across the following integral
Here $n>1$ is an integer. I was curious as to what its asymptotic form would be. It seems to be a bit slowly growing as a function of $\omega$ which makes sense since the integrand is highly oscillatory but I don't see how to show this. I did come up with an analytic form for the roots and tried to find out how much area was approximately under each spike via approximation from within by triangles but this didn't seem too fruitful as the expressions started to get a bit unwieldy.
