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,那末,思想就整体地把握了问题,并且能创造地思索问题的解法。”在解某些代数题时,对代数式赋予某种几何意义,然后转化为几何问题,再寻求解题思路,常会得到令人满意的效果。一个代数问题转化为几何问题,并不怎么容易的。完成这样的“转化”,对解答者的要求是:必须具备良好的几何素质,具有把知识进行正迁移的能力,善于把原来的代数式(或问题)进行恒等(或等价)变形, The mathematician Steen said. “If a particular problem can be transformed into a graph, then the idea grasps the problem as a whole, and can creatively think of the solution to the problem.” When solving some algebraic problems, give the algebraic formula some kind of geometric meaning, and then Converting to a geometric problem and then seeking a solution to the problem will often yield satisfactory results. It is not easy to convert an algebraic problem into a geometric problem. To complete such “transformation”, the requirements of the solver are: must have good geometric qualities, have the ability to transfer knowledge positively, and be good at transmuting the original algebraic equation (or problem) with an equal (or equivalent),
