State L'hospital theorem

In mathematics, more specifically calculus, L'Hôpital's rule or L'Hospital's rule (French: [lopital]) provides a technique to evaluate limits of indeterminate forms. Application (or repeated application) of the rule often converts an indeterminate form to an expression that can be easily evaluated by substitution.
