不动点问题是近几年高考中考查的热点,此类试题具有较强的综合性,在高考试卷中失分较为严重.通过对近几年高考试题的研究发现,不动点问题主要和数列、函数、方程、解析几何等紧密联系,对高中数学教学提出了更高的要求,认真研究不动点问题的解题策略,有助于提高高中数学教学效果.一、不动点问题在数列中的应用数列是高考的重要考点,也是综合性较强的题型之一,求数列的通项公式是数列的基础.在解决此类问题时,往往可以从研究不
The fixed point problem is a hot spot in the college entrance examination in recent years, such questions have a strong comprehensive, in the entrance examination papers in the more serious loss.Through the study of college entrance examination papers in recent years found that the fixed point problem and Series, functions, equations, analytic geometry and so on, puts forward higher requirements for mathematics teaching in senior high schools, studies the problem-solving strategies of fixed point problem seriously, and helps to improve the high school mathematics teaching effect. The number of applications in the series is an important test of the college entrance examination, but also one of the more comprehensive questions, the general formula for the number of columns is the basis of the sequence.In solving such problems, often can not from the study
