有些数学题目若全盘考虑难度太大,为此可动中觅静,静中求动,动静结合,这种方法若处置得当,既能优化解题过程,又能提高思维品质,为难题巧解铺就坦途.1静中求动有些题目参数较多,不妨让一些参数“动”起来,引入新的变量,从而打开解题突破口.例1已知正数a,A,b,B,c,C满足条件a+A=b+ If some mathematics topics are considered too difficult, it can be moved quietly, statically seeking action, and combining movements. If this method is handled properly, it will not only optimize the problem-solving process, but also improve the quality of thinking. Paved on the way. 1 static seeking some parameters of the subject, you may wish to let some parameters “move” up, introduce new variables, so as to open the problem solving breakthrough. Example 1 known positive number a, A, b, B, c, C satisfies the condition a+A=b+
