转化与化归思想方法,就是在研究和解决有关数学问题时采用某种手段将问题通过变换使之转化,进而使问题获得解决的一种方法。转化与化归思想在高考中占有相当重要的地位,可以说比比皆是,如未知问题向已知问题的转化,复杂问题向简单问题的转化,不同数学问题之间的转化,实际问题向数学问题的转化。本文将结合2012年的高考试题,从以上几个不同的方面加以阐述。
The method of transforming and reverting to thinking is a way to solve the problem by researching and solving mathematical problems by transforming them with some means. Transformation and return to thought occupy a very important position in the college entrance examination can be said abound, such as the unknown to the known problems, complicated problems to simple problems, different mathematical problems between the practical problems to mathematics Conversion of the problem. This article will be combined with the 2012 college entrance examination questions, from the above several different aspects to be elaborated.
