Hi

I am working on how to get the last closed field lines of a moving magnetic field (as a bit of background). Anyhow, as part of it, I have to integrate

$\displaystyle \frac{c\Omega \cos(K)+\sin(K)(c^2+\Omega^3K)}{2c^2\Omega(\cos(K) +K \sin(K)}dK$

Anybody have any ideas how I would go about doing this?
