特殊值法是指在解题过程中,根据问题所给的全部信息,通过推理、分析、判断,选取包含在问题中的某个特殊值,或某个特殊情形,经过简单的推理、判断或运算来求解的一种解题方法。利用特殊值法往往能够更加轻松地整合题目中所给出的信息,进而做到迅速解题。下面简单介绍在解题过程中如何利用特殊值法提升高中数学的解题效率。一、善于利用特殊数值,在特殊中找寻一般解法高中数学题尤其是填空和选择题,往往都存在一
Special value method refers to the process of solving problems, according to all the information given by the problem, through reasoning, analysis, judgment, select the inclusion of a special value in the problem, or a special case, after a simple reasoning, judgment or A solution to the problem solving method. The use of special value method is often able to more easily integrate the information given in the title, and thus quickly solve the problem. The following is a brief introduction of how to use special value method to improve the solving efficiency of high school mathematics in solving problems. First, good use of special values, in the special to find the general solution High school math problems, especially fill in the blanks and multiple-choice questions, there is often a
