分类讨论解题策略

Discuss the Solution Tactics Classifily

分类讨论是一种数学思想,也是一种解题策略.高等数学中的有关函数、极限、微分、积分、级数等内容的题目,当涉及对象比较复杂或范围广时,解题时要进行分类讨论.函数的零点、驻点、极值点、拐点等往往作为分类讨论的分界点.

Classification discussion is a kind of mathematical thought,and is also a kind of problem solving strategy.When it comes to more complex objects or range, to solve the problem of function, limit, differential, integral and seriesin the advanced mathematics ,we should do the calssification discussion. The zero point of function, the stagnation point,the extreme point and the inflection point are often looked as the demarcation points of the classification discussion.
