三十六计中有“明修栈道暗度陈仓”的妙计,而“点解法”恰好体现了这一计的精髓。“点解法”明面上是设出点的坐标,似乎要通过联立方程组,从而求出点的坐标,但实际上却是巧妙地通过设出点的坐标,直接解答问题,可以称之为“暗度陈仓”。对于许多解析几何问题的求解,也可以不需要联立方程,只通过设出点的坐标,就可以直接解答问题,这是解析几何中的“点解法”。应用“点解法”可以大大简化计算过程,在解答问题的同时提高解题效率,是一
In the thirty-six plan, there is a good idea of “minor repair of the darkness of the plank road”, and “point solution” precisely reflects the essence of this plan. The “point solution method” is to set the coordinate of the point on the surface. It seems that the coordinate of the point is obtained by the simultaneous equations, but in fact, it is ingeniously solving the problem by setting the coordinates of the point. Call it “darkness warehouse”. For solving many analytical geometric problems, simultaneous equations may not be needed. The problem can be solved directly by setting the coordinates of the point. This is the “point solution” in analytical geometry. The application of “point solution method” can greatly simplify the calculation process and improve the problem solving efficiency while solving problems.
