问:面对数学难题,自己常常感到无从下手,该如何突破?Q博士:所谓难题,其实是难在怎么想,而不是知识点.做题时式子的全部变形,直接体现在题目所问的和题目所给的条件到底差异在哪,大家要根据式子的差距,决定思维的方向,寻找解题的程序和策略.另外,如何把所要解决的问题转化为已经解过的问题,怎样在陌生的情境下,从题意的挖掘开始,一步一步找到解决问题的途径是破解难题的关键,这就需要同学们减小跨度,自设阶台,分阶而上,分割踩分,最终实现解题.
Q: In the face of math problems, I often feel that I can not start, how to break? Dr. Q: The so-called problem, in fact, is difficult to think about, rather than knowledge points. In the end, we should decide the direction of thinking according to the difference between the formulas and find out the procedures and strategies for problem solving. In addition, how to translate the problem to be solved into the solution to the problem that has already been solved? In unfamiliar situation, starting from the excavation of the title, step by step to find a solution to the problem is the key to solving the problem, which requires students to reduce the span, set the stage, step by step, split step by step, the final To solve the problem.
