how could we calculate the follwing integral ??(adsbygoogle = window.adsbygoogle || []).push({});

[tex] \int_{0}^{\infty} \frac{ K(x)}{Q(x)}dx [/tex]

here K(x) and Q(x) are POLYNOMIALS , of course if we had an integral over all R instead of [tex] (0 , \infty ) [/tex] we could apply Cauchy's residue theorem

i think there is a 'closed circuit' to perform the integral and you have to add a term logx inside the denominator but not completely sure.
