This document discusses L'Hopital's Rule, which can be used to evaluate limits that produce indeterminate forms like 0/0 or ∞/∞. It explains that L'Hopital's Rule involves taking the derivative of the numerator and denominator and re-evaluating the limit. However, it cautions that the rule can only be applied to quotients that result in indeterminate forms, and certain functions must first be rewritten in quotient form before applying the rule. Examples of limits that can and cannot use L'Hopital's Rule are provided.
