3、mmercialactivities,militaryoperationsandscientificandtechnologicalresearches.1-AWhatismathematics数学来源于人类的社会实践,比如工农业生产,商业活动,军事行动和科学技术研究。Andinturn,mathematicsservesthepracticeandplaysagreatroleinallfields.Nomodernscientificandtechnologicalbranchescouldberegularlydevelopedwithouttheapplicati
4、onofmathematics.反过来,数学服务于实践,并在各个领域中起着非常重要的作用。没有应用数学,任何一个现在的科技的分支都不能正常发展。Fromtheearlyneedofmancametheconceptsofnumbersandforms.Then,geometrydevelopedoutofproblemsofmeasuringland,andtrigonometrycamefromproblemsofsurveying.Todealwithsomemorecomplexpracticalproblems,manestablishedandthensolve
5、dequationwithunknownnumbers,thusalgebraoccurred.很早的时候,人类的需要产生了数和形的概念。接着,测量土地问题形成了几何学,测量问题产生了三角学。为了处理更复杂的实际问题,人类建立和解决了带未知数的方程,从而产生了代数学。Before17thcentury,manconfinedhimselftotheelementarymathematics,i.e.,geometry,trigonometryandalgebra,inwhichonlytheconstantsareconsidered.17世纪前,人类局限于只考虑常数的初

7、7世纪工业的快速发展推动了经济技术的进步,从而遇到需要处理变量的问题。从常量到变量的跳跃产生了两个新的数学分支-----解析几何和微积分,他们都属于高等数学。Nowtherearemanybranchesinhighermathematics,amongwhicharemathematicalanalysis,higheralgebra,differentialequations,functiontheoryandsoon.现在高等数学里面有很多分支,其中有数学分析,高等代数,微分方程,函数论等。Mathematicianss
