在某些不等式的求证中,如果能恰当地引入参数,赋予该参数以一定的数学意义,让其参与运算,往往思路清晰,方法简捷。在某些不等式的求证中,如果能恰当地引入参数,赋予该参数以一定的数学意义,如直线的斜率等,让其参与运算,往往思路清晰,方法简捷。这种方法对培养学生思维的灵活性、独创性、深刻性,提高学生的思维品质,具有积极的意义。本文结合例题加以
In the confirmation of some inequalities, if the parameters can be properly introduced, giving the parameters a certain mathematical meaning, let them participate in the operation, often clear thinking, the method is simple. In the confirmation of some inequalities, if the parameters can be properly introduced, this parameter is given a certain mathematical meaning, such as the slope of a straight line, so that it can participate in the calculation, often with clear ideas and simple methods. This method has a positive meaning in cultivating students 'flexibility, originality and profoundness in thinking and improving students' thinking quality. This article combined with examples to be
