How To Find The Limit At Infinity

This calculus video tutorial explains how to find the limit at infinity.  It covers polynomial functions and rational functions.  The limit approaches zero if the function is heavy at the bottom or if the degree of the denominator exceeds that of the numerator.  The limit approaches a constant value if the degree of the numerator and the denominator is the same.  If the numerator has a higher degree, the limit will approach positive or negative infinity.
