在新一轮课程改革中,向量被引入了高中数学课程,这极大地丰富了高中数学的内涵,也拓宽了高中数学解题的思维空间.由于向量是既有大小又有方向的量,向量的各种运算既有代数意义又有几何意义,因此,以向量为工具可以沟通代数、几何的许多分支,建立起向量与代数、几何的多元联系.同时,由于向量自身具有一套优良的运算体系,运用 In the new round of curriculum reform, the vector was introduced into the high school mathematics curriculum, which greatly enriched the connotation of high school mathematics, but also broaden the thinking space of high school mathematics problem solving.As the vector is both the size and direction of the vector, Therefore, vector can be used as a tool to communicate algebra and many branches of geometry to establish multiple connections between vectors and algebra and geometry.At the same time, since the vector itself has an excellent set of operations System, use
