美国数学家斯蒂恩说:“如果一个特定的问题可以被转化为一个图形,那么,思维就整体地把握了问题,并且能创造性地思索问题的解法。”因此,将问题转化为一个图形,把问题中的条件和结论直观地、整体地表露出来,是一种十分重要的解题方法。
American mathematician Steen said: “If a particular problem can be transformed into a graph, then thinking can grasp the problem as a whole, and can creatively ponder the solution of the problem.” Therefore, turning the problem into a graph, Exposing the conditions and conclusions of the problem visually and integrally is a very important method of solving problems.
