向量融数形于一体,具有代数形式(坐标表示)与几何形式(有向线段表示)双重特征1向量思想开拓了从另一个角度探究各几何量之间的联系的新途径,使轨迹问题的解决变得更直接.让我们在运用向量知识解决轨迹问题的训练中,深刻领会向量工具的实际价值,提高应用向量的意识,形成一种融合 The vector fusion number is integrated into one, with algebraic forms (coordinate representation) and geometric forms (directed line representations). The dual feature 1 vector idea opens up new ways to explore the connection between geometric quantities from another perspective, making the trajectory problem The solution becomes more direct. Let us use the knowledge of vector to solve the problem of trajectory training, deeply understand the real value of vector tools, increase the awareness of application vectors, and form a fusion.
