向量作为新教材的一个亮点,倍受关注.由于向量集数、形于一体,涉及了代数、几何、三角等多门课程,而向量方法特别便于研究有关直线和平面的各种问题,因此对向量的学习和研究一定要溶于这些课程,并把握好向量与各课程间的交汇点,发挥其作用. Vectors as a bright spot of new textbooks have attracted much attention. Because of the number of vectors and their shapes, they involve many courses such as algebra, geometry, and triangles, and vector methods are particularly convenient for studying various problems concerning straight lines and planes. The study and study of vector must be dissolved in these courses, and grasp the intersection of the vector and the various courses to play its role.
