在高中数学学习活动开展过程中,平面向量当中的最值以及范围问题一直是学习的重点和难点。学生在学习的过程中掌握了此类问题的学习方法不仅能够提高分析问题和解决问题的能力,同时还能在最大的程度上提高灵活运用知识点的能力。基于这样的背景之下,本文对平面向量的最值问题和范围问题进行了分析,以此来提高学生的学习效率和学习成绩。 In the process of high school mathematics learning activities, the issue of the maximum value and range in the plane vector has always been the focus and difficulty of learning. Learning methods that students have mastered in this process can not only improve the ability to analyze problems and solve problems, but also improve the ability to use knowledge points to the greatest degree. Based on this background, this paper analyzes the problem of the value and scope of the plane vector, in order to improve students’ learning efficiency and learning achievement.
