同学们在平时的解题过程中,在学习和研究例、习题的解法时,如果关注和留意解法中所蕴含的数学思想和方法,分析题目解法的一般性和特殊性,时时对题目进行总结和反思,当然会对解题能力的提高有很大帮助.下面举几例一题多解,从题的变式中一看便知哪个是巧解,哪个是通解.所以要求同学们在平时做题时,既要关心巧解,又要寻求通解. Students in the usual problem-solving process, learning and research cases, exercises solution, pay attention to and pay attention to the solution contained in the mathematical ideas and methods to analyze the generality and specificity of the topic solution, from time to time to summarize the subject And reflection, of course, will improve the ability to solve problems great help. Here are a few examples of a multi-solution, from the variant of the title to see which is clever solution, which is general solution. Therefore, students are required in peacetime Do the question, it is necessary to care about clever solution, but also to seek general solution.
