在高中数学教学中,向量的相关知识是一项重点内容,也是江苏数学高考的主要考查内容之一.其中平面向量的数量积是C级考点;平面向量的概念,平面向量的加法、减法及数乘运算,平面向量的坐标运算,平面向量的平行与垂直都是B级考点;平面向量的应用是A级考点.近年来,高考中关于向量考查着 In high school mathematics teaching, vector knowledge is a key content, but also one of the main test content of Jiangsu math entrance exam, in which the number of plane vector is C grade test center; the concept of plane vector, vector addition, subtraction and Number of multiplication operations, coordinate calculation of plane vector, planar vector parallel and vertical are B-level test sites; plane vector application is A-class test sites. In recent years, the college entrance examination on vector test
