经过了一轮复习,各个板块的知识点象一盘珍珠散落在盘子中,如果想找到一根彩线将它们串起来,以达到融会贯通的效果,那么向量可以说是最合适的.向量具有双重身份,借助向量的“数”的特征可用代数的方法来研究几何性质;借助“形”的特征可使代数的抽象问题直观化.以这一知识和方法为媒 After a round of review, the knowledge of each plate as a pearl scattered on the plate, if you want to find a color line to string them together to achieve the effect of mastery, then the vector can be said to be the most suitable vector has a dual Identity, with the help of the “number ” feature of the vector algebraic method can be used to study the geometric properties; with the help of “form ” features can make the abstract problem of algebra intuitive .And this knowledge and method as a medium
