谈导数在经济问题中的应用

运用数学知识能较好地解决经济领域中的许多问题。而导数是高等数学中的重要概念,其在经济领域中的应用越来越广泛,并且导数已经成为经济分析中最为实用的工具之一,如边际成本、需求弹性、成本的最小化、利润的最大化等都是通过导数解决的。所以,学习导数的概念并熟练掌握导数的应用尤为重要。本文将利用导数对经济中的实际问题进行边际分析、弹性分析,从而为企业经营者进行科学决策提供重要依据。     

导数在经济数学中的教学与应用探讨

随着经济的发展,对经济学的研究要用到越来越多的数学知识,许多经济学的概念、理论都与数学密切相关,导数在经济学的研究中有着深远而广泛的影响.而数学与经济学特别是微观经济学具有密切的联系,利用数学定量分析特别是建立数学模型解决经济领域方面的问题成为经济学整个理论体系中的一个组成部分.导数作为高等数学中的一个重要概念,无疑是经济学分析的一个重要工具.运用导数可以对经济活动中的实际问题进行边际分析、需求弹性分析和最值分析,从而为企业经营者科学决策提供量化依据.     

导数理论在经济分析中的应用探讨

数学知识来源于实际生活,也在实际生活中应用。作为一种数学工具,导数被广泛应用于经济领域。随着市场经济的快速发展,经济问题的解决需要利用越来越多的数学知识。导数是经济分析的重要工具,优化分析经济活动中的实际问题。本文主要对导数理论进行概述,并在此基础上探究导数理论在经济分析中的具体应用。     

导数的应用

导数是微分学中最基本的概念,本文通过导数在求切线方程中的应用、利用导数求出函数的单调性、利用导数求函数的最大值和最小值等方面的应用分析,说明了导数的重要性。     

导数在经济中的应用研究

在高中数学学习中,导数这个工具非常有用,导数与经济的关系非常密切,尤其在微观经济学中,我们可以看到导数的影子。本文首先对导数在经济学以及经济分析中的应用进行了分析与研究。对于经济学中的边际问题和弹性问题进行了举例分析,从而阐述了数学思想方法在处理经济学问题的优势,突出了导数处理经济问题的重要性,从而为社会经济发展作出自己的贡献。

漏洞百出的教育

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help?     

Western and Eastern culture differences in commercial field

The communication of people partially is the communication of cultures. Culture has a direct effect on international commercial activities in all aspects. Different conceptions about time, space, equality, law and the like, lead people to deal with things in different ways. So to know cultures of the counterpart is to facil-itate our enterprises so as to have a smooth and successful communication in commercial activity.     

只要努力,不要后悔

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love.     

浅谈移民问题

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject.     

Sister Carrie, an Adherent of Desires

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities.
