数列是按照一定顺序排列的数,有关数列问题的考查一般涉及数列的通项公式、前项和以及数列的递推公式等,而极限思想是一种用极限概念分析问题和解决问题的数学思想,通过对问题极端状态的讨论,简化计算,使得解题效率最大化。因此,运用极限思想,可以巧妙解答数列问题。一、巧用极限思想,妙解数列求和问题在求解数列问题时,经常会遇到不等式证明类题型,要求在不等式问题中解决代数式与常数大小问题,这时可以运用极限思想去构造一个以该常数为极限的
The numbers are arranged according to a certain order. The examinations of the numbers generally involve the general formulas of the numbers, the precedents and the recursion formulas of the numbers, and the limit idea is a kind of mathematical thought that analyzes and resolves the problems with the limit concept , By discussing the extreme state of the problem, simplifying the calculation and maximizing the efficiency of problem solving. Therefore, the use of limit thinking, you can cleverly solve the sequence of questions. First, clever use of limit thinking, wonderful solution to the problem of sequence summation In solving the sequence of problems, often encounter inequalities to prove the type of questions, require the inequality problem to solve algebraic and constant size problems, then you can use the limit idea to construct a The constant is the limit
