平面向量是高中新教材的新增内容,它是新的思想方法和数学工具,在许多领域中有着广泛应用.巧妙地运用平面向量解数学问题往往更简捷、更明了、更易被学生理解.因此,只有加强应用的训练,注意把向量与函数、三角、几何等内容联系起来,形象思维与逻辑思维相结合,学生才会构建出自 Plane vector is the new content of new high school textbooks. It is a new way of thinking and mathematics tools. It has been widely used in many fields. Cleverly using plane vectors to solve mathematical problems is often simpler, clearer and easier for students to understand. Only strengthen the application of training, pay attention to the relationship between vector and function, triangle, geometry, etc., image thinking and logical thinking combined, students will build
