数学讨论题内容广泛,逻辑性强,是考查学生分析问题和解决问题能力的有效题型。面对讨论题,好多考生无从着手,普遍感到难。究其原因,主要在于如何确定讨论“对象、范围、分界点”和如何“避免、简化”讨论不得要领。本文特就上述问题介绍若干解题策略,供参考。一、确定讨论“对象、范围、分界点”的若干方法 1.“使运算能继续进行”确定法。例1 解关于x的不等式 The mathematics discussion questions are wide in content and logical, and are effective questions that examine students’ ability to analyze problems and solve problems. In the face of discussion questions, many candidates are unable to start and generally feel difficult. The reason for this is mainly how to determine the “object, scope, and demarcation point” and how to “avoid and simplify” the discussions. This article describes a number of problem-solving strategies for the above issues, for reference. First, determine a number of methods to discuss the “object, scope, demarcation point” 1. “Making calculations can continue to” determine the law. Example 1 Solution of inequality about x
