高中数学解题除了掌握应有的知识,还要具备必要的数学思想和方法.这其中等价转化的思想尤为重要,可以说数学解题过程就是实施等价转化的过程,通过等价转化能把陌生的问题转化为熟悉的问题、复杂的问题转化为简单的问题,最终使问题得以解决.实施等价转化又有许多种具体的方法,如参数法、换元法、数形转化法等等,其中有一种方法是通过取对数,将问题进行等价转化的,姑且称为取对数法.这一方法还不太为大家所熟悉和掌握,这是因为平时对数问题接触的比
In addition to mastering due knowledge, high school mathematics problem solving must have the necessary mathematical ideas and methods, of which the thought of equal value transformation is especially important. It can be said that the mathematical problem solving process is the process of carrying out the equivalent transformation. Transform unfamiliar questions into familiar ones, complex ones into simple ones, and finally solve the problems. There are many kinds of concrete methods to implement equivalence transformation, such as parametric method, metamorphosis method, numerical transformation method, etc. , Etc. One of the methods is to logarithmically convert the question to the equivalent logarithm method, which is not yet well known to all and mastered because of the usual logarithmic problem ratio
