向量既有大小,又有方向,是数与形的完美结合。向量是一个重要概念,能和数一样进行运算,作为一种数学工具,越来越被人们所重视。向量由于具有“形”和“数”的两重特点,使它成为中学数学知识内容的中介。向量作为一种数学工具,高考命题在向量与其他知识的结合处设计试题已屡见不鲜。在高中数学教学中应重视和应用好这一有力的工具,以拓展学生的想象力,激发他们的创新能力,提高 Both the size of the vector, but also the direction, is the perfect combination of numbers and shapes. Vector is an important concept that can be operated like a number. As a kind of mathematical tool, more and more people pay attention to it. Due to the dual characteristics of “” and “number ”, vector becomes an intermediary of the content of mathematical knowledge in high school. Vector as a mathematical tool, college entrance examination proposition in the vector and other knowledge at the junction of the design of the exam has been commonplace. In high school mathematics teaching should pay attention to and apply this powerful tool in order to expand the imagination of students to stimulate their ability to innovate and improve
