My Gauss-Legendre integrator gives the same to 6 places.

I'm sorry, I omitted a key component of the integrand in my initial
post. I have corrected it in another message to this thread.

I've only just started learning Mathematica, but so far my attempts
at solving it with Mathematica fail. But that's not the point; I
need to implement the integration using my own code (Visual Basic
in this case) so I need to know what integration technique is most
efficient for this problem of: a definite integral over a finite
interval with huge orders of magnitude oscillations in tiny part of
the interval.
