随着高考改革的深入,向量在中学数学中的地位也愈来愈显著,学好向量并进行运用,已成为很多同学的共识.那么如何学好向量呢?这就要抓住向量学习中的关键点,抓住它就犹如抓住向量学习的主线一样,其他问题也就迎刃而解,因此本文试以选择题为例来加以说明. With the deepening of the college entrance examination reform, the role of vectors in middle school mathematics has become more and more significant. Learning the vectors and applying them have become the consensus of many students. How do you learn the vector? This must capture the key points in vector learning. Grabbing it is like grasping the main line of vector learning. Other problems will be easily solved. Therefore, this paper tries to explain it by taking multiple choice questions as an example.
