1、 09 级毕业论文答辩稿 辅助函数在数学中的应用 学 号: 902091126 组 别: 第( 9)组 内容提要 高等数学中运用辅助函数就像是在几何中添加辅助线,在数学中的应用是非常重要的 .当我们遇到特殊的题目时,用常规方法可能比较复杂 .这时我们就需要构造辅助函数,就如同架起一座桥梁,不需要大量的算法就可以得到结果 .因此,学习构造辅助函数对于我们证明、解题是非常有帮助的 .本论文是从证明定理与解题两方面分别来阐述辅助函数的 作用,通过本文我们会更好的了解辅助函数在数学中的应用 . 关键词: 辅助函数 定理 证明 Abstract Summary: The auxiliary functi
2、on is applied to higher mathematics as adding auxiliary line in geometry. Its applications of mathematics is very important. Use the conventional method may be complicated when we encounter special problems. Then we can construct the auxiliary function like a bridge do not need a lot of algorithm to
3、 get the result. Therefore, it is very helpful for us to study the structure of auxiliary function to prove and solve problem. This paper expounds the application of auxiliary function respectively from two aspects of theorem proving and problem solving. Through this paper we will know better in mathematics. Keywords: auxiliary function theorem testify
