在学生求解高中数学题目时,经常会遇到多种情况的复杂问题,这时候就需要对各种情况进行分类讨论,分类求解,最终综合解答,这也是分类解答的原理。分类讨论法是数学解题中重要的逻辑思维方法和解题策略,主要是通过分类讨论和整体归纳解答的解题方法,可以避免逻辑混乱,使解过程清晰明了。该方法主要用于函数和平面解析几何。 When students solve high school mathematics problems, they often encounter complex problems in a variety of situations. At this time, it is necessary to categorize and discuss various situations and solve the problems in a comprehensive way, which is also the principle of the categorical solution. Classification discussion method is an important logical thinking method and problem solving strategy in mathematical problem solving. It mainly avoids logical confusion and clarifies the solution process through classification and discussion and solving problems of the whole solution. This method is mainly used for function and plane analytic geometry.
