简化或避免分类讨论的若干策略
Some Methods of Simplifying or Avoiding the Reasoning by Classify
【摘要】 分类讨论用于解数学题有时会很繁复,为克服这一缺点,可用消去参数、整体换元、数形结合、变换主元、补集分析等方法简化或避免分类讨论。
【Abstract】 The reasoning by classify is complicated sometimes when it is applied to solve mathematics problems. We often utilize elimination, entire change of variable, unity quality to figure, change of main variable, analysis complementary set in order to overcome this defect.
