For a given real number x>0, it is possible to count the number of primes less than or equal to x. This number is said to be a function of x even though no simple algebraic formula is known for computing it (without counting) when x is known. 对于一个给定的实数x>0，数出小于或者等于x的素数 的个数是有可能的。这个数称为x的函数，尽管还没 有一个简单代数式可以由已知的x计算(不通过计数求) 出它的值。
These are merely devices for describing special relations in a quantitative fashion. Mathematicians refer to certain types of these relations as functions. 这些只是以定量的方式描述特定关系的方法。数学家 将这些关系中的某些类型视作函数。 In this section, we give an informal description of the function concept. A formal definition is given in Section 3. 在本节中，我们给出一个非正式的描述函数的概念。 在第3节给出一个正式的定义 。
EXAMPLE 1. The force F necessary to stretch a steel spring a distance x beyond its natural length is proportional to x. That is, F=cx, where c is a number independent of x called the spring constant. 把一个钢制的弹簧拉伸到超过其自然长度的距离为x 时所需要的力F与x成正比。即，F=cx,这里c是不依赖 与x的数，叫做弹性系数。 This formula, discovered by Robert Hooke in the mid17th century, is called Hooke’s law, and it is said to express the force as a function of the displacement.

几何的学习使学生在思考问题时更周密、审慎，他们 将不会盲目接受任何结论.
2－B Some geometrical terms
A solid is a three-dimensional figure. Common exaБайду номын сангаасples of solids are cube, sphere, cylinder, cone and pyramid. A cube has six faces which are smooth and flat. These faces are called plane surfaces or simply planes. 立体是一个三维图形，立体常见的例子是立方体，球
This is evident from the fact that they require study of geometry as a prerequisite to matriculation in those schools. 许多居于领导地位的学术机构承认，所有学习这个数 学分支的人都将得到确实的受益。

平面上的闭曲线当其中每点到一个固定点的距离均相 当时叫做圆。固定点称为圆心。

Let P denote the set of all positive integers. Then P is itself an inductive set because (a) it contains 1, and (b) it contains x+1 whenever it contains x. Since the members of P belong to every inductive set, we refer to P as the smallest inductive set. 用P表示所有正整数的集合。那么P本身是一个归纳 集，因为其中含1，满足(a)；只要包含x就包含x+1, 满足(b)。由于P中的元素属于每一个归纳集，因此P 是最小的归纳集。
Quotients of integers a/b (where b≠0) are called rational numbers. The set of rational numbers, denoted by Q, contains Z as a subset. The reader should realize that all the field axioms and the order axioms are satisfied by Q. For this reason, we say that the set of rational numbers is an ordered field. Real numbers that are not in Q are called irrational. 整数a与b的商被叫做有理数，有理数集用Q表示，Z 是Q的子集。读者应该认识到Q满足所有的域公理和 序公理。因此说有理数集是一个有序的域。不是有 理数的实数被称为无理数。

Mathematical Puzzles
Welcome to my selection of mathematical puzzles. The math puzzles presented here are selected for the deceptive simplicity of their statement, or the elegance of their solution. They range over geometry, probability, number theory, algebra, calculus, trigonometry, and logic. All require a certain ingenuity, but usually only pre-college math. Some puzzles are original. Explaining how an answer is arrived at is more important than the answer itself. To this end, hints, answers, and fully worked solutions are provided, together with links to related mathematical topics. Further references are provided with many of the solutions. The puzzles are intended to be fun, with an educational element.
