I am staring at an integral of the form(adsbygoogle = window.adsbygoogle || []).push({});

[tex]

\int \frac{sin(at)}{(1 + bsin^{2}(at))^{1/2}} dt

[/tex]

which I have generated for myself (in attempting to model the behaviour of a particle in an oscillating field). I can't see a sensible substitution to try, at present. I could hunt down a standard integral, perhaps, but I suspect something obvious is evading me...

Any hints? Also, any suggestions for brushing up on solving integrals of this sort? I'm a bit rusty :-)

Cheers!
