This document discusses L'Hopital's rule, a technique used in calculus for evaluating limits of indeterminate forms. Specifically, it states that if the limit of f(x)/g(x) as x approaches c results in an indeterminate form of 0/0 or infinity/infinity, and if f(c) = g(c) = 0 and both f'(c) and g'(c) exist, then the limit can be evaluated as the ratio of the derivatives f'(c)/g'(c). It also presents a more generalized form of L'Hopital's rule that requires only that the individual limits of f(x), g(x), f'(x), and g'(x
