数学概念的建立是分析解决数学问题,提高数学能力以及形成数学思想的前提。因此,在数学教学中,教师应重视概念教学。在高中数学中,平面向量数量积是一个重要的概念,新课标和高考对其都有较高的要求。探讨了对平面向量数量积概念的理解及其应用。
The establishment of mathematical concepts is the premise of analyzing and solving mathematical problems, improving mathematical ability and forming mathematical ideas. Therefore, in mathematics teaching, teachers should pay attention to the concept of teaching. In high school mathematics, the number of plane vector quantity is an important concept, the new curriculum standard and college entrance examination have higher requirements. This paper discusses the concept and application of the concept of number vector of plane vectors.
