Abstract: | With the examples in university entrance examination in the year 2012, we discuss how to solve the nonlimit problems with the method of limit: 1 ) the determination of the figures of functions, 2) the exploration of the range of parameters, 3 ) the probe into the maximum value or minimum value of functions. |

Keywords: | Limit test questions of university entrance examination figure parameters max-imum value or minimum value |
