高中数学学习过程中经常碰到命题恒成立与命题成立等问题.如果在学习过程中不仔细推敲每种题型的解法,很容易混淆这两种问题.本文围绕这两种情形进行分析,旨在帮助学生在学习过程中能培养学生对方法的提炼,加强思维灵活性和创造性的训练,使学生真正提高分析问题和解决问题的能力.一、命题恒成立问题命题恒成立问题,这里阐述的主要是利用最值法解决不等式恒成立问题.
In high school mathematics learning process, we often encounter problems such as propositional constant establishment and propositional establishment. If we do not carefully scrutinize the solution of each question type in the learning process, it is easy to confuse these two problems. This paper analyzes these two situations and aims In helping students in the learning process can train students to refine methods, strengthen the flexibility of thinking and creative training, so that students really improve the ability to analyze problems and solve problems. First, propositional constant establishment problem Proposition constant establishment problems, elaborated here It is mainly to use the most value method to solve the inequality problem.
