《数学通报》中的“数学问题解答”栏,对数学竞赛训练和解题方法研究很有指导意义.笔者引其中几题,谈谈学习体会.1问题新颖,具有探究性在“问题解答”栏中,问题新颖,有代表性.有的问题还为我们提供了探索情境,在学习中引导读者探究.例1467题(2003年12月号问题):如图,四边形ABCD
The “Mathematics Questions Answers” column in the “Medical Bulletin” is very instructive for the study of mathematics competition training and problem solving methods. The author quotes several questions and talks about the learning experience. 1 The problem is novel and inquiryful in the “problem answer”. In the column, the questions are novel and representative. Some questions also provide us with a situation to explore and guide readers to explore during the study. Example 1467 (December 2003 issue): Figure, Quadrilateral ABCD
