初中阶段,同学们已经对不等式形成了初步的认识,高中阶段,对不等式数学内容的衔接,一方面是让同学们对数学知识形成更加系统的认识,另一方面是巩固同学们的知识基础,促使同学们形成完整的知识体系。但高中阶段不等式相关内容难度增加,对同学们的解题能力有更高的要求。因此,掌握不等式解题技巧,对同学们的后续学习具有十分重要的意义。一、不等式恒成立的解题技巧 At the junior high school stage, students have formed a preliminary understanding of inequality. In high school, the convergence of inequalities in mathematics content enables students to have a more systematic understanding of mathematical knowledge on the one hand, and consolidates the students’ knowledge base. On the other hand, Promote students to form a complete knowledge system. However, the high school stage inequality related content more difficult to improve the students’ ability to solve problems have higher requirements. Therefore, mastered the inequality problem solving skills, the students follow-up study is of great significance. First, the inequality constant problem-solving skills
