参数变换方法在数学分析中的应用

Application of the Method of Transformation of Parameter in Mathematics Analysis

参数变换就是在原问题中引入辅助性的新变数(一般称为参数),把要证明或求解的问题的关系式转化为参数的关系式,然后对参数进行运算,求得新问题的解,最后再消去参数,得到原问题的解的一种方法。通过数学分析中的常见例题探讨这种变化方法,可以有效地提高解题能力。

Parameter transformation a way that introduces a supplementary new variable（is usually called parameter） in primal problem,converts be proved of be solved relation of the problem to relation of the parameter,then computes the parameter to gain the solution of the new problem,finally eliminates parameter to gain the solution of the primal problem.In mathematical analysis,the method posses extensive of use.The paper refers to the method of transformation through common examples in mathematical analysis.
