解析几何中的最值问题，实质上是曲线知识与函数内容的综合运用．尽管知识与方法都是已经学习过的内容．但因其综合性强、解法的灵活多样．能力要求较高，而使学生在理解、掌握、应用上深感困难．本文拟就解析几何中最值问题，给出几种较为典型的解法，以期达到开拓解题思路． The most value problem in analytic geometry is essentially the integrated use of the knowledge of the curve and the content of the function. Although both knowledge and method are already learned. But because of its comprehensive, flexible solution. High ability requirements, leaving students in understanding, mastery, application of deep difficulties. This paper intends to resolve the most value problems in geometry, and gives several typical solutions, in order to achieve the idea of ​​developing solutions.
