莫德尔说过:“在数学美的各个属性中,首先要推崇的大概是简单性了.”数学是和“简约”非常有渊源的,我们在解决数学问题时,就是要追求数学的简约美,要在众多的解法中尽量探索出最为简便的解法,体现了数学解题的价值取向,也体现了数学的基本功.在解决有关向量的数量积问题时,如果涉及到图形有中心点,则往往把向量转化到含有中心点的向
Modell has said: “Among the various attributes of mathematical beauty, the first one to be respected is simplicity.” Mathematics is very much related to “Simple ”, and when we solve mathematical problems, we are pursuing mathematics The simplicity of the United States to explore the most convenient solution in many solutions, embodies the value orientation of mathematical problem solving, but also reflects the basic skills of mathematics.In solving the problem of the quantity of the product of the vector, if it involves the graphics center Point, the vector is often transformed to contain the center of the direction
