“向量是既有大小,又有方向的量,它既有代数特征,又有几何特征,通过向量可以实现代数问题与几何问题的相互转化,向量是数形结合的桥梁。”这段话向广大师生讲述了向量在中学数学和现实生活中的广泛应用处理的两个方向,即代数形式化和几何图形化, “Vector is both the size and the direction of the amount of both the algebraic features, but also geometric features, through the vector algebraic problems and geometric problems can be transformed into each other, the vector is a combination of digital bridge. ” This paragraph The words to the majority of teachers and students about the vector in the high school mathematics and real life in a wide range of applications dealing with two directions, that is, algebra formal and geometric shapes,
