What is L''hospital''s rule used for? + Example
2014/10/07· L''hopital''s rule is used primarily for finding the limit as x->a of a function of the form f(x)/g(x), when the limits of f and g at a are such that f(a)/g(a) results in an indeterminate form, such as 0/0 or oo/oo. In such cases, one can take the limit of the derivatives of those functions as x->a. Thus, one would calculate lim_(x->a) (f''(x))/(g''(x)), which will be equal to the limit of the
