大一期末复习和考研复习必备高等数学基本知识点一、函数与极限1、集合的概念⑴、全体非负整数组成的集合叫做非负整数集（或自然数集）。

记作N⑵、所有正整数组成的集合叫做正整数集。

记作N+或N+。

⑶、全体整数组成的集合叫做整数集。

记作Z。

⑷、全体有理数组成的集合叫做有理数集。

记作Q。

⑸、全体实数组成的集合叫做实数集。

记作R。

⑶、邻域：设α与δ是两个实数，且δ＞0.满足不等式│x-α│＜δ的实数x的全体称为点α的δ邻域，点α称为此邻域的中心，δ称为此邻域的半径。

2、函数⑴、函数的定义：如果当变量x在其变化范围内任意取定一个数值时，量y按照一定的法则f总有确定的数值与它对应，则称y是x的函数。

变量x的变化范围叫做这个函数的定义域。

通常x叫做自变量，y 叫做函数值（或因变量），变量y的变化范围叫做这个函数的值域。

注：为了表明y是x的函数，我们用记号y=f(x)、y=F(x)等等来表示。

这里的字母"f"、"F"表示y与x之间的对应法则即函数关系,它们是可以任意采用不同的字母来表示的。

如果自变量在定义域内任取一个确定的值时，函数只有一个确定的值和它对应，这种函数叫做单值函数，否则叫做多值函数。

这里我们只讨论单值函数。

⑵、函数相等由函数的定义可知，一个函数的构成要素为：定义域、对应关系和值域。

由于值域是由定义域和对应关系决定的，所以，如果两个函数的定义域和对应关系完全一致，我们就称两个函数相等。

⑶、域函数的表示方法a)：解析法：用数学式子表示自变量和因变量之间的对应关系的方法即是解析法。

例：笛卡尔直角坐标系中，半径为r、圆心在原点的圆的方程是：x2+y2=r2b)：表格法：将一系列的自变量值与对应的函数值列成表来表示函数关系的方法即是表格法。

例：在实际应用中，我们经常会用到的平方表，三角函数表等都是用表格法表示的函数。

c)：图示法：用坐标平面上曲线来表示函数的方法即是图示法。
