剑桥 IGCSE 进阶数学（0606）是一门严谨的大学预科数学课程，专为具备扎实 IGCSE 数学基础并希望衔接 A Level 数学的 11 年级学生设计。该课程大纲扩展了核心代数技能，引入了微积分，并培养高级解题技巧。全面了解大纲内容是取得高分的第一步。本文将对 CIE 进阶数学课程大纲进行逐专题解析，突出关键概念、典型题型与复习重点。
1. Syllabus Overview and Assessment Structure | 大纲概览与评估结构
The Additional Mathematics syllabus (0606) is assessed through two equally weighted written papers, Paper 1 and Paper 2, each lasting 2 hours and carrying 80 marks. Both papers cover the full syllabus content, and calculators are permitted in both. Paper 1 includes 10–12 compulsory questions of varying lengths, while Paper 2 features 10–12 questions as well, often with slightly more emphasis on problem solving and application. There is no coursework component. The syllabus content is organised into fourteen main topics, from functions to integration, and questions frequently combine multiple topics within a single item.
进阶数学课程（0606）通过两份权重相同的书面试卷进行评估，试卷一和试卷二各持续 2 小时，满分均为 80 分。两份试卷均覆盖全部课程内容，且均可使用计算器。试卷一包含 10 至 12 道必答题，长度不一；试卷二同样有 10 至 12 道题，但往往更偏重问题解决与应用。无课程作业环节。课程内容分为十四个主题，从函数到积分，试题常常在一个题目中综合多个主题。
The grade boundaries for a top grade (A*) typically require around 80–85% of the total marks, reflecting the high standard expected. Students must therefore aim for accuracy across the entire syllabus.
高分等级（A*）的分数线通常需达到总分的 80–85%，反映出预期的高标准。因此学生必须在整个课程范围内追求精确度。
2. Functions and Relations | 函数与关系
ue in its range. Common notations include f(x) = 2x + 3. Understanding domain restrictions — such as x ∈ ℝ, x ≥ 0, or x ≠ 2 — ) = g(f(x)) and inverse functions f⁻¹(x) are tested regularly; remember that the graphs of a function and its inverse are reflections in the line y = x. The modulus function |x| and its piecewise definition are also examined.
函数 f 将其定义域内的每个输入值唯一映射到值域中的一个输出值。常见记法为 f(x) = 2x + 3。理解定义域的限制——例如 x ∈ ℝ、x ≥ 0 或 x ≠ 2——至关重要。本课程还要求你通过考虑图像形状等方式找出函数的值域。复合函数 (gf)(x) = g(f(x)) 与反函数 f⁻¹(x) 是常见考点；请记住，原函数与其反函数的图像关于直线 y = x 对称。绝对值函数 |x| 及其分段定义式也是考试内容。
y = f(x) and solve for y. The domain of the inverse is the range of the original function.
求反函数时，在 y = f(x) 中互换 x 与 y，然后解出 y。反函数的定义域即为原函数的值域。
3. Quadratic Functions and Equations | 二次函数与方程
ed square form a(x − h)² + k, from which the vertex (h, k) and the axis of symmetry x = h can be read directly. The discriminant Δ = b² − 4ac determines the nature of the roots: two distinct real roots if Δ > 0, one repeated real root if Δ = 0, and no real roots if Δ < 0. Solving quadratic equations efficiently by factorisation, completing the square, or the quadratic formula is essential.
二次函数 f(x) = ax² + bx + c（a ≠ 0）是许多进阶数学问题的基石。你必须能将其书写为配方完成式 a(x − h)² + k，由此可直接读出顶点 (h, k) 和对称轴 x = h。判别式 Δ = b² − 4ac 决定根的性质：Δ > 0 时有两个不等实根，Δ = 0 时有一个重根，Δ < 0 时无实根。熟练运用因式分解、配方法或求根公式解二次方程至关重要。
x = [−b ± √b² − 4ac] / 2a
Quadratic inequalities such as ax² + bx + c > 0 are solved by sketching the parabola and identifying the intervals where the curve lies above or below the x-axis.
求解如 ax² + bx + c > 0 的二次不等式时，需画出抛物线并确定曲线位于 x 轴上方或下方的区间。
4. Indices, Surds and Logarithms | 指数、根式与对数
aᵐ ÷ aⁿ = aᵐ⁻ⁿ, (aᵐ)ⁿ = aᵐⁿ, and rationalise denominators containing surds such as 1/(2 + √3 denominator by the conjugate. The transition to logarithms is seamless: logₐ y = x means aˣ ase rule logₐ b = (log b)/(log a) appear frequently. Solving exponential equations like e²ˣ = 5 often requires taking natural logs on both sides.
指数与根式的运算法则在代数与数值运算中均有考查。你必须能化简包含 aᵐ × aⁿ = aᵐ⁺ⁿ、aᵐ ÷ aⁿ = aᵐ⁻ⁿ、(aᵐ)ⁿ = aᵐⁿ 的表达式，并能通过乘以共轭式将分母含有根式的分数（如 1/(2 + √3)）有理化。对数的引入衔接流畅：logₐ y = x 意味着 aˣ = y。自然对数 ln x = logₑ x 与换底公式 logₐ b = (log b)/(log a) 经常出现。求解 e²ˣ = 5 等指数方程时，常需两边取自然对数。
Remember to check that the arguments of logarithmic functions are positive; any solution giving log(negative) must be rejected.
请牢记对数函数的自变量必须为正；任何导致 log(负数) 的解都应舍去。
5. Polynomials, Factors and Rational Functions | 多项式、因式与有理函数
g one integer root through trial (often a divisor of the constant term) and then performing long division or inspection to obtain a quadratic factor. The Remainder Theorem, f(b) = R, allows quick evaluation of remainders. Partial fractions are introduced for proper rational expressions: a fraction with a linear denominator, (px + q)/((x + a)(x + b)), is split into the sum of simpler fractions. Cases with repeated linear factors are also included.
因式定理指出，若 f(a) = 0，则 (x − a) 是多项式 f(x) 的一个因式。你需要能够通过试根（常取常数项的约数）找到一个整数根，然后进行长除法或观察法得到二次因式，从而分解三次式。余数定理 f(b) = R 可快速求出余数。部分分式适用于真分式：分母为线性因式的分式 (px + q)/((x + a)(x + b)) 可拆分为若干简单分式的和。含重复线性因式的情形也包含在内。
Polynomial division can be set out like long division of numbers. Always express the final answer with quotient and remainder clearly indicated, especially when the degree of the numerator exceeds that of the denominator.
多项式除法可按类似数值长除法的格式演算。最终答案务必清晰注明商式和余式，尤其当分子次数高于分母次数时。
6. Coordinate Geometry: Straight Lines and Graphs | 坐标几何：直线与图像
can be written in gradient-intercept form y = mx + c or point-gradient form y − y₁ = m(x − x₁). Parallel lines have equal gradients, while perpendicular lines satisfy m₁m₂ = −1. You will also find the midpoint and distance between two points. Beyond lines, you are expected to sketch and interpret graphs of functions, including determining asymptotes of rational functions and using intersections of graphs to solve equations.
本专题进一步深入探讨直线图像。过两点 (x₁, y₁) 与 (x₂, y₂) 的直线斜率为 m = (y₂ − y₁)/(x₂ − x₁)。直线方程可用斜截式 y = mx + c 或点斜式 y − y₁ = m(x − x₁) 表示。平行线斜率相等，垂直线满足 m₁m₂ = −1。你还需要会求中点及两点间距离。除直线外，大纲要求你能够绘制并解读函数图像，包括确定有理函数的渐近线以及利用图像交点解方程。
, the x-coordinates of the intersection points are the solutions. This idea is often used to estimate roots of equations that cannot be solved algebraically.
用图像法解 f(x) = g(x) 时，交点横坐标即为解。此法常用于估计无法通过代数方法求解的方程的根。
7. Trigonometry and Circular Measure | 三角学与弧度制
mulas. All six trigonometric ratios (sin, cos, tan, cosec, sec, cot) are introduced, along with their exact values for angles like 30°, 45° and 60°. You need to know fundamental identities such as sin²θ + cos²θ = 1, tan θ = sinθ/cosθ, and their rearranged forms. Solving trigonometric equations within a given interval, often requiring factorisation or use of identities, is a core skill. The graphs of sin, cos and tan — including their amplitudes, periods and asymptotes — must be recognised.
进阶数学中的角度主要采用弧度制，其中 π 弧度 = 180°。弧长公式 s = rθ 与扇形面积公式 A = ½r²θ 为必记公式。六个三角比（sin、cos、tan、cosec、sec、cot）及其在 30°、45°、60° 等角度的精确值均会涉及。你需要掌握基本恒等式，如 sin²θ + cos²θ = 1、tan θ = sinθ/cosθ 及其变形。在给定区间内解三角方程，往往需要因式分解或运用恒等式，这是一项核心技能。同时必须认识 sin、cos 与 tan 的图像，包括其振幅、周期及渐近线。
Arc length: s = rθ | Sector area: A = ½r²θ
ally states degrees. Watch for the domain: typical intervals are 0 ≤ θ ≤ 2π or −π < θ < π.
除非题目明确要求角度制，否则答案一律使用弧度制。注意定义域：常见区间为 0 ≤ θ ≤ 2π 或 −π < θ < π。
8. Permutations and Combinations | 排列与组合
This chapter deals with counting arrangements and selections. The factorial notation n! .. × 1 is used. The number of permutations of r objects from n distinct objects is ⁿPᵣ = n!/(n−r)!, and the number of combinations is ⁿCᵣ = n!/(r!(n−r)! e to determine when order matters (permutations) and when it does not (combinations). Real‑ nclude arranging letters, forming committees, and lottery selections. Restrictions such as “two people must sit together” or “one item is excluded” are tackled by treating certain objects as a block or by adjusting the counting process.
本章涉及排列与选择方式的计数。阶乘记法 n! = n × (n−1) × ... × 1 将被使用。从 n 个不同物体中选取 r 个的排列数为 ⁿPᵣ = n!/(n−r)!，组合数为 ⁿCᵣ = n!/(r!(n−r)!）。你必须能判断何时顺序重要（排列），何时不重要（组合）。实际情境包括字母排列、组建委员会以及彩票选号。对于“两人必须坐在一起”或“某物被排除”等限制条件，可通过将特定物品视为整体或调整计数过程来求解。
When the question uses words like “arrange”, “sequence” or “line up”, think permutations; “choose”, “select” or “committee” usually indicate combinations.
当题目使用 “arrange”、“sequence” 或 “line up” 等词时，考虑排列；“choose”、“select” 或 “committee” 通常提示组合。
9. Sequences and Series | 数列与级数
on difference d, the nth term is uₙ = a + (n−1)d, and the sum of the first n terms is Sₙ = n/2 [2a + (n−1)d]. For a GP with first term a and common ratio r (r ≠ 1), uₙ = arⁿ⁻¹ and Sₙ = a(1−rⁿ)/(1−r). The condition |r| and may involve solving simultaneous equations derived from given relations between terms.
学习两种特定的数列：等差数列（AP）与等比数列（GP）。对于首项为 a、公差为 d 的等差数列，第 n 项为 uₙ = a + (n−1)d，前 n 项和为 Sₙ = n/2 [2a + (n−1)d]。对于首项为 a、公比为 r（r ≠ 1）的等比数列，uₙ = arⁿ⁻¹，前 n 项和为 Sₙ = a(1−rⁿ)/(1−r)。当 |r| < 1 时，无穷等比级数之和为 S∞ = a/(1−r)。题目常要求找出特定项、项数或和，并可能涉及利用项与项之间的关系构建并解联立方程。
Be careful with the order of operations: raise r to the power (n−1) before multiplying by a. Also, the sum‑to‑infinity formula only converges when |r| < 1.
注意运算顺序：先将 r 进行 (n−1) 次方，再乘以 a。此外，无穷和公式仅在 |r| < 1 时收敛。
10. Vectors in Two Dimensions | 二维向量
form or using unit vectors i and j. You will add and subtract vectors, find the magnitude |v| = √x² + y², and scale vectors by a constant. Position vectors, displacement vectors, and relative velocity are included. The dot product a • b = |a||b| one being a scalar multiple of the other, and perpendicular vectors satisfy the component‑based condition that the sum of the product of their corresponding i‑components and j‑components equals zero: a ⊥ b a₁b₁ + a₂b₂ = 0. This is a straightforward criterion that students must apply confidently.
向量表示既有大小又有方向的量。在进阶数学中，向量以列向量形式或使用单位向量 i 与 j 表示。你将进行向量的加减运算，求其模 |v| = √x² + y²，并用常数对向量进行缩放。位置向量、位移向量与相对运动也包含在内。点积 a • b = |a||b|cos θ 不在本大纲范围内；取而代之，判断平行向量时，依据其中之一是否为另一向量的标量倍数；对于垂直向量，满足对应分量乘积之和为零：若 a₁b₁ + a₂b₂ = 0，则 a ⊥ b。这是一个直接明了的判据，学生应能熟练应用。
e a common point B and are parallel (i.e., AB = k BC). This is a common geometry question.
共线性可通过证明向量 AB 与 BC 共点 B 且平行（即 AB = k BC）来求证。这是几何题中的常见问法。
11. Differentiation | 微分
d the constant multiple rule allow you to differentiate polynomial functions term by term. Key applications include finding the gradient of a tangent, the equation of the tangent or normal at a point, and identifying stationary points (where dy/dx = 0). By testing the sign of the first derivative on either side of a stationary point, or using the second derivative d²y/dx², you can determine whether the point is a local maximum, local minimum, or a point of inflection. Connected rates of change are also tested: for example, if V = f(r) and dr/dt is known, then dV/dt = (dV/dr)(dr/dt).
微分用于求曲线上任意一点处的梯度。xⁿ 的导数为 nxⁿ⁻¹，此法则可推广至任意有理指数。和法则与常数倍法则使你能够逐项微分多项式函数。主要应用包括求切线斜率、一点处切线或法线方程，以及确定驻点（dy/dx = 0 的点）。通过检验驻点两侧一阶导数的符号，或利用二阶导数 d²y/dx²，可以判断该点是局部极大值、局部极小值还是拐点。关联变化率也是考查内容：例如，若 V = f(r) 且已知 dr/dt，则 dV/dt = (dV/dr)(dr/dt)。
If y = xⁿ, then dy/dx = nxⁿ⁻¹
Always present the equation of a tangent or normal in a simplified linear form. For a normal, remember that its gradient is −1/(dy/dx).
给出的切线或法线方程务必化为最简线性形式。对于法线，须谨记其斜率为 −1/(dy/dx)。
12. Integration and Its Applications | 积分及其应用
tion. Definite integration calculates the exact area under a curve between two bounds: Area = ∫ₐᵇ y dx. You will also handle simple cases where integration gives a natural logarithm: ∫ (1/x) dx = ln |x| + C. The area between a curve and the y‑ ferentiation and integration: v = ds/dt, a = dv/dt, and conversely v = ∫ a dt, s = ∫ v dt.
积分是微分的逆过程。xⁿ（n ≠ −1）的不定积分为 (xⁿ⁺¹)/(n+1) + C，其中 C 为积分常数。定积分用于计算曲线在两边界之间下方的精确面积：面积 = ∫ₐᵇ y dx。你也会处理积分结果为自然对数的简单情形：∫ (1/x) dx = ln |x| + C。可能要求计算曲线与 y 轴之间或两曲线之间的面积。运动学应用专题通过微分与积分将位移 s、速度 v 和加速度 a 联系起来：v = ds/dt, a = dv/dt，反之 v = ∫ a dt, s = ∫ v dt。
When using integration to find an area, always sketch the region first. Pay attention to areas below the x‑axis, as the integral gives a negative value; use absolute values to obtain the true area.
使用积分求面积时，务必先画出区域草图。注意 x 轴下方的区域，因为积分给出负值；应使用绝对值以获得真正面积。
