会做题和懂概念,是两回事。很多在美国读高中的学生,因式分解会做,斜率的意思也知道,标准差的定义能背出来,可一到考试,题目换个问法就不知道从哪里下手;上周做对的题,这周改一个条件又卡住了。《美高数学解题手册》要补的,正是'会解题'这一步。本书不是题海,也不替代课本和老师,而是挑出美国高中数学课程赖以搭建的五十多道经典'母题',把每一道从头讲到底。全书17章分三部分:代数(第1-8章:方程与不等式、直线与线性关系、方程组与矩阵、多项式与因式分解、二次方程与抛物线、有理式根式与复数、函数指数与对数、数列与应用题建模),几何(第9-13章:角与平行线证明、三角形、圆、周长面积与体积、坐标几何与几何变换),统计与概率(第14-17章:描述统计、概率与计数、概率分布、抽样与统计推断初步),覆盖 Algebra 1、Algebra 2、Geometry 和高中统计课的核心内容。每道母题都按同样的八段展开:题目、识别模型、通用思路、一步一步解、变式演化、一题多解、易错点与普适提醒、母题小结。其中'变式演化'是全书的招牌--一道题一次只改一个条件,看清解法哪里不变、哪里必须跟着变。旗舰章第5章用一道二次方程走完因式分解、开平方、配方、求根公式四种解法,再画成抛物线;只改常数项,它就从两个实根变成重根,再变成一对复数根。全书贯穿三条主线:代数里任何方程都用'化简→归类→选法→解→验根'五步处理;统计里任何数据都用'看类型→画图→算中心与离散→选对工具'四步处理;几何以两栏式证明为骨架,每一步结论都写明理由,理由用'中文(English)'对照。常用公式尽量讲清推导,忘了也能自己重新推出来。本书为中英双语桥接设计:正文以中文讲解,关键术语随文附英文,并用脚注拆解常用词根词缀,帮助读者听懂美国课堂、读懂英文考题;符号与写法采用美国高中惯例,并在容易混淆处与国内写法对照。全书不涉及微积分,也不讲计算器操作,所有计算都手写完整。插图为原创黑白线条图,题目、数据和插图全部原创。本书适合在美国读高中、或准备赴美读高中的中文母语学生,也适合想帮孩子衔接美国数学课程的家长和老师。它为 AP® Precalculus、AP® Calculus 和 AP® Statistics 打好代数、几何与统计基础,其中统计与概率部分可直接衔接 AP® Statistics 的前期内容。本书不是 AP® 考试备考书,不含 AP® 题型训练。预备微积分与微积分的内容,请见同系列《美高预备微积分解题手册》和《美高微积分解题手册》。AP® 和 Advanced Placement® 是美国大学理事会(College Board)的注册商标,College Board 未参与本书的出版,也不为本书背书。

    Many high school students understand the ideas in their math class and still get stuck on the problems. They can factor a trinomial, explain what a slope means, and recite the definition of a standard deviation, yet a test question worded a little differently leaves them unsure where to start. A problem they solved last week stops them cold when one condition changes. Knowing t...
