谈牛顿─莱布尼兹公式

谈牛顿─莱布尼兹公式滕文凯微积分第二基本定理──牛顿──莱布尼兹公式把微分与积分从概念与计算上同时联系起来，是使微积分理论形成一个体系的一个重要标志。以下从几个方面出发，谈一谈对牛顿──莱布尼兹公式的认识。１把求定积分的问题化为求ｆ（ｘ）的原函数问题...     

牛顿—莱布尼兹公式的“引导发现式”教学

介绍了"引导发现式"教学方法在牛顿—莱布尼兹公式教学中的具体运用。根据现行高等数学内容,提出通过创设情境、适时点拨、巧选角度、激励求知等引导学生自己发现问题、探索牛顿—莱布尼兹公式。     

牛顿-莱布尼兹公式随想

牛顿—莱布尼兹公式是微积分中最重要的定理之一。它是由英国科学家牛顿和德国数学家莱布尼兹在17世纪发现的。牛顿稍先于莱布尼兹发现该公式,不过当时没有正式发表,而莱布尼兹发现该公式后立即就发表了,所以,该公式当时命名为莱布尼兹公式。而当牛顿逝世后,人们在他的手     

对“微积分基本定理”的认识和理解

微积分基本定理(又称牛顿一莱布尼兹公式)是微积分中最重要的定理,它是由英国数学家牛顿(1642—1727)和德国数学家莱布尼兹(1646—1716)在十七世纪首先发现的,被命名为牛顿一莱布尼兹公式。它的出现标志着微积分的完成,成为数学发展史上的一个里程碑。定理命名中的“基本”二字,已表明了它在微积分中的地位,因此,对每个学习微积分的人来说。都应该对建立微积分基本定理的历史有所了结,进一步加对定理的认识和理解。本就此问题作一些相应的介绍。     

微积分的历史、现状和未来(二)

上面我们叙述了牛顿在建立微积分方面的贡献,下面是莱布尼兹工作的简介.3 莱布尼兹的微积分莱布尼兹自述,他是1674年发明微分法的.10年后,即1684年莱布尼兹发表了他的第一篇微分学论文《一种求极大值、极小值和切线的新方法,不受分数量及无理量阻挠的奇特算法》(拉丁文全名 Nova methodus pro maximis et minimis,itemque tangentibus,quae nec fractas,nec irrationales quanti-tares moratur,et singulare pro illis calculi genus),刊登在《教师学报》(Acta eruditorum)上.这是数学史上第一篇正式发表的微积分文献(注意,牛顿曾自述他在1665年发明了流数术,但

对两个积分转换公式的几何意义的探讨

在积分学中有两个著名的公式,其意义和应用都是十分重要的。这两个公式就是牛顿—莱布尼兹公式和格林公式。为了讨论的方便,我们列出这两个公式及其成立的条件。 1.牛顿—莱布尼兹公式:设函数f(x)在[a,b]上连续,如果F(x)是f(x)在[a,b]上的一个原函数,则     

漫谈微积分的产生与发展

提起微积分,人们自然会想到英国的牛顿(Newten,1642￣1727)和德国的莱布尼兹(Leibniz,1646￣1716),这主要是因为他们提出了微积分的基本概念和运算方法,发现了微积分的内在联系,建立了著名的牛顿—莱布尼兹公式.但是微积分的产生与发展,远不止这些,它有着久远的历史.1.微积分产

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.
