How to Find Horizontal Asymptotes of Rational Functions

Let f ( x ) = p ( x ) q ( x ) , where p(x) is a polynomial of degree m with leading coefficient a, and q(x) is a polynomial of degree n with leading coefficient b. There are three cases:

Case 1: If m>n, then f has no horizontal asymptotes.
Case 2: If m=n, then y = a b is the horizontal asymptote of f.
Case 3: If m
How to Find Vertical Asymptotes of Rational Functions

If there are any common factors between the numerator and the denominator, then cancel all common factors. Set the denominator equal to zero then solve for x.

This integral poses a challenge.
Ordinarily integrating rational functions can be solved using the Hermite-Ostrogradski method. However, in the following integral, the coefficients β 0 , . . . , β 4 are not integers. (Hence, the Hermite-Ostrogradski method would not be appropriate).
Note: Expanding the integrand (trying to solve the integral using a partial fraction decomposition) is (because of the nature of the physical problem described by this integral) an inappropriate solution to this case.

I'm trying to find out under which conditions does a sum of a rational function f(n) converges, with f(x)=A(x)B(x), with degB>degA and X,B(X)0.
Who knows?
