Most of the students have problem about limit at infinity:

Please read this portion carefully. This will be applicable for rational function lim x→±∞

 p( x)q( x )  

where p(x) is called numerator and q(x) is called denominator.

As for example x

3+2

 x2

+1 here  p ( x )= x

3+2  and de!ree of p(x) " # q ( x )= x

2+1  and

de!ree of q(x) " $.

%o usin! this procedure (which is shown below) do all other mathematics.
