| Abstract: | In the Mathematics teaching of senior middle school, we can answer the follow-ing questions by the way of getting extrem value of function: 1. the distance between lines in dif-ferent space. 2. the manium and minium value of the distance between the point on the faper bendlines to known lines. 3. To get extreme value with enchanging elements. |
