随着新课改要求的提出,对于我们在综合素质方面有着更高的要求,而高中数学作为一门逻辑性强、相对较难学习的课程,我们在平常学习中要注意总结各种解题方法,实现巧妙解答的目的,这样也能很好地提高我们的自信心,培养自己的数学学习兴趣,在数学学习中不断取得新的突破。在高中数学学习中,关于不等式证明、求取值范围、求极值等方面的试题的解答过程都非常繁琐,如果不借助于一定的手段,很难实现巧解,而构造出特殊的函数并运用在这些试题的解答中往往可以起到事半功倍的效果。本文主要探讨了函数构造法的具体运用,将我平时学习中的经验和体会进行了总结,以期起到互相学习的目的,实现共同进步。
With the proposed new curriculum reform requirements, we have higher requirements in terms of overall quality, and high school mathematics as a logical, relatively difficult to learn course, we should pay attention to sum up various problems in the usual learning The method achieves the purpose of ingenious solutions, which can also improve our self-confidence, cultivate our interest in mathematics learning, and continuously make new breakthroughs in mathematics learning. In high school mathematics learning, the answers to questions about inequality proofs, range of values, and extremum are very tedious. If you do not rely on certain means, it is difficult to achieve sensible solutions and construct special functions. Applying to the answers to these questions can often have a multiplier effect. This article mainly discusses the specific use of the function construction method, summarizes my experience and experience in peacetime learning, in order to achieve the purpose of mutual learning and achieve common progress.
