The necessary and sufficient conditions (not limited to series) for judging the convergence of Cauchy limit existence criterion are mainly applied in the following aspects:

(1) series

(2) Series of several terms

(3) Function

(4) improper integral

(5) Function sequence and function term series

Math function, limit and continuity for postgraduate entrance examination include: compound function, concept and nature of limit, comparison of infinite order, operation of limit, determination of parameters in limit, calculation of asymptote, continuity of function, types of discontinuous points and judgment of boundedness.
