数列是高中数学中重要内容,在高考中涉及考题多为中等及以上难度.数列是特殊的函数,这部分内容中蕴含的数学思想方法有函数与方程思想、分类讨论思想、化归转化思想、数形结合思想等.高考试题中所涉及的知识综合性强,既有较繁的运算又有一定的技巧,解题时要注意从整体去把握.数列求和一直是数列试题的考察重点,也是解答的难点.掌握良好的解题方法能在考试中缩短解题时间,提升解题的准确性,实现考试成绩的提高,对高中数学学习意义重大.
The number of high school math is an important part of the content in the college entrance examination questions are mostly medium and above the difficulty of the number of columns is a special function of this part of the content contains mathematical thinking and function of the equation thinking, The number of combination with ideology, etc. The college entrance examination questions involved in the comprehensive knowledge, both more complicated operations and a certain skill, problem-solving should pay attention to grasp from the whole.Series summation has been the focus of the series of examinations, Is also a difficult problem to answer.Good way to solve problems in the examination can shorten the time to solve the problem, improve the accuracy of problem-solving, to achieve the test scores improve, high school mathematics learning is of great significance.
