在各地近几年的高考模拟试题中,频繁地出现这样三类问题:“向量”问题、“折线距离”问题及“面积”问题.每每遇到这类题学生往往不知所措,难以入手,所以非常容易出错.究其原因:一是问题本身新颖、知识点比较综合,对学生思维要求比较高;二是问题以能力立意为宗旨,问题中蕴含着丰富的数学思想与方法下面笔者就这三类问题 In recent years, college entrance examination simulation questions in recent years, such problems appear frequently: “vector ” question, “polyline distance ” and “area ” problems often encountered such problems students often do not know It is difficult to start with, so it is very easy to make mistakes. The reason: First, the problem itself is new, knowledge points more comprehensive, higher demands on students thinking; Second, the problem is to capacity for the purpose of conception, the problem contains rich mathematical ideas The following method with the author on these three issues
