c uses the ratio of the respective derivatives and is better known as L'Hôpital's rule.
In complete metric spaces, Cauchy sequences always have one of these. Those of a function can be found using the sandwich theorem and a typical definition is that for some delta region around x, f(x) will be within some epsilon region. A technique for finding indeterminate ones of functions of form f(x)/g(x) c uses the ratio of the respective derivatives and is better known as L'Hôpital's rule. These are often used to give define derivatives. For 10 points, name this concept often given as the value of a function as it approaches a certain point.
