After doing my homework on testing for convergence/divergence in infinite series, I noticed that if you are testing for divergence of a rational function, if the difference in the degree of the functions (bottom - top) [itex]\leq[/itex] 1, then it is divergent, and if the difference in the degree of the functions is > 1, then it is convergent. I can post this proof if someone wants.(adsbygoogle = window.adsbygoogle || []).push({});

I was just wondering if there is a name for this concept..
