3. Exhaustive derivation of uncertain conditions in mathematical problems (classified discussion ideas).
Every mathematical conclusion has its own conditions, and the use of every mathematical method often has its scope of application. Among the mathematical problems we encounter, the conclusions of some problems are not unique, the conclusions of some problems cannot be studied in a unified form in solving problems, and the known quantities of some problems are given in the form of letters, so different values of letters will also affect the solution of problems. Judging from the above problems, the method of solving problems and the means of transformation are consistent, that is, all the problems studied are divided into several categories according to the characteristics and requirements of the topic and transformed into several small problems to solve. This mathematical idea of classifying according to different situations and then studying and solving them one by one is called classified discussion thought. [2]
