在数学中,有些问题往往难以直接求出答案.若在不改变所求量的情况下,巧妙改变题目的条件,实现题目的等效转换,再去求解,会使问题变得简单.下面列举几例来说明转换法在解题中的重要作用.例1若m、n互为倒数,则mn2-(n-1)=.分析:本题考查同学们对倒数、乘方及乘法法则的理解和运用情况 In mathematics, some problems are often difficult to find the answer directly.If you do not change the amount of demand, the conditions of the subject change subtly to achieve the equivalent conversion of the problem, and then to solve the problem will make the problem simple. Several examples to illustrate the conversion method in the problem-solving important role.Example 1 If m, n reciprocal each other, then mn2- (n-1) =. Analysis: This question examines the students reciprocal, power and multiplication law understanding And use the situation
