向量具有几何和代数双重性,与几何和代数关系密切,它在立体几何、三角、数列等各种知识模块中都可能出现,是连接众多知识的桥梁,利用它可以有效解决很多问题.但向量题又较灵活,学生因此在高考中失分严重.作者通过2013年安徽理9的探究和延伸,给出了求解向量的常用方法和技巧,揭开了向量神秘的面纱,提高学生对向量的认知和信心.
The vector has the duality of geometry and algebra, and it is closely related to geometry and algebra. It may appear in various knowledge modules such as three-dimensional geometry, trigonometry and sequence, etc. It is a bridge connecting many knowledge and can solve many problems effectively. The problem is more flexible and students therefore lose points seriously in the entrance examination.The author through the exploration and extension of Anhui Li 9 in 2013, gives the commonly used methods and skills to solve the vector, opened the veil of vector mystery, to improve students’ Cognition and confidence.
