To calculate the limit at infinity, we need to compare the highest power of denominator and numerator.
There are in general 3 types:
1. highest power (after simplify) of denominator greater than numerator, the limit often goes to 0.
2. highest power of dominator and numerator are the same, the limit is the highest term coefficient.
3. highest power of denominator smaller than numerator, the limit often goes to infinity (or negative infinity).
