解答数学题需要选择一个容易攻克的突破口,并以此作为解题的切入点,由点及面,逐步解决所有问题.这需要在分析题目的已知条件和所求问题特征的基础上,正确寻找已知条件与所求问题特征之间的隐含关系式作为解题的一个切入点,成为成功解题的关键. Solving math problems requires choosing a breakthrough point that is easy to overcome, and using this as an entry point for problem solving. From point to area, it solves all problems step by step. This requires correct analysis of the problem’s known conditions and the characteristics of the problem. Finding the implicit relation between the known conditions and the characteristics of the problem to be sought as an entry point to solve the problem becomes the key to successful problem solving.
