不等式在高中数学中是非常重要的内容,我们一般可以根据要解的不等式或者要证明的不等式题目所提供的各种信息,选择合适的解法和证明方法。在解和证明不等式时,同学们往往会感到特别困难,而利用构造法来解、证明不等式,使得问题的解决达到事半功倍的效果。什么是构造法?构造法是指在解决数学问题时,寻找与问题相关的内在联系,恰当地构造数学模型,将原问题化归为
Inequality is a very important part in high school mathematics. Generally, we can choose appropriate solutions and proofs based on the inequality to be solved or the information provided by the inequalities to be proved. In solving and proving inequalities, students often feel particularly difficult, but the use of structural method to solve, prove that inequality, making the problem is solved to achieve a multiplier effect. What is the construction method? Construction method is to solve the mathematical problems, to find the internal linkages associated with the problem, the appropriate mathematical model, the original problem is classified as
