1. Syllabus Overview and Assessment Structure | 课程概览与评估结构
The CAIE IGCSE Additional Mathematics (0606) syllabus is examined through two equally weighted written papers – Paper 1 and Paper 2 – each lasting 2 hours and carrying 80 marks. A scientific calculator is allowed in both papers. The syllabus does not include any coursework. All questions are compulsory and are drawn from the entire subject content. The assessment aims to test not only knowledge of techniques but also the ability to apply mathematical reasoning and model real-world situations.
CAIE IGCSE 进阶数学（0606）课程通过两份等值的笔试——试卷一和试卷二——进行考核，每份试卷均为 2 小时，满分 80 分。两场考试均可使用科学计算器。该课程不包含任何课程作业。所有题目均为必答题，覆盖全部教学内容。评估不仅考查技巧掌握情况，还测试运用数学推理与建模实际情况的能力。
Grades are reported on an eight-point scale from A* to G. To excel, students must be fluent in algebraic manipulation, comfortable working with abstract functions, and capable of linking multiple concepts within a single problem. Time management is crucial, as Papers 1 and 2 often include multi-step problems that require careful planning.
成绩以 A* 到 G 的八个等级报告。要想脱颖而出，学生必须熟练进行代数运算，自如地处理抽象函数，并能在单个问题中联结多个概念。时间管理至关重要，因为试卷一和试卷二经常包含需要周密规划的多步骤问题。
2. Functions | 函数
A function is a rule that maps each input value from its domain to exactly one output value in its range. The syllabus expects you to understand the terms domain, range, one-one function and inverse function. Notation such as f(x) = 2x + 5 and f: x ↦ 2x + 5 must be used confidently. You will also need to form composite functions, such as gf(x), and solve equations involving compositions.
函数是一种将定义域中的每个输入值唯一映射到值域中一个输出值的规则。大纲要求你理解定义域、值域、一一函数和反函数等术语。须能自信地使用 f(x) = 2x + 5 和 f: x ↦ 2x + 5 等记号。你还需要构造复合函数，例如 gf(x)，并求解涉及复合的方程。
Finding the inverse function f⁻¹(x) by rearranging y = f(x) to make x the subject and then swapping variables is a core skill. Remember that a function must be one-one on its given domain to have an inverse. Restricted domains are often used to ensure invertibility. Sketching graphs of functions and their inverses, reflecting in the line y = x, is also examined.
通过重排 y = f(x) 使 x 成为主项，然后交换变量来求反函数 f⁻¹(x) 是一项核心技能。记住，函数在给定定义域上必须是一一对应的才存在反函数。经常通过限制定义域来确保可逆性。绘制函数及其反函数的图像，并反映出关于直线 y = x 的对称性，也属于考查范围。
3. Quadratic Functions | 二次函数
Quadratic functions of the form f(x) = ax² + bx + c are central to the syllabus. You must be able to complete the square to rewrite the expression in the form a(x – h)² + k, which reveals the vertex (h, k) and axis of symmetry x = h. The discriminant Δ = b² – 4ac determines the nature of the roots: two distinct real roots if Δ > 0, one repeated root if Δ = 0, and no real roots if Δ < 0.
形如 f(x) = ax² + bx + c 的二次函数是课程核心。你必须能够通过配方法将表达式改写为 a(x – h)² + k 的形式，这能显示顶点 (h, k) 和对称轴 x = h。判别式 Δ = b² – 4ac 决定根的性质：若 Δ > 0 则有两个不等实根，若 Δ = 0 则有一个重根，若 Δ < 0 则无实根。
You will also solve quadratic inequalities such as ax² + bx + c > 0 by sketching the parabola and identifying the intervals where the curve is above or below the x-axis. Questions often link quadratic functions with coordinate geometry or with finding the maximum or minimum value of an expression.
你还将通过绘制抛物线并确定曲线在 x 轴上或下方的区间，来求解诸如 ax² + bx + c > 0 的二次不等式。题目常将二次函数与坐标几何联系起来，或要求求表达式的最大值或最小值。
4. Equations, Inequalities and Graphs | 方程、不等式与图像
Beyond quadratics, the syllabus covers solving simultaneous equations where one equation is linear and the other is non-linear, often involving circles or parabolas. Substitution is the key method. You must also be able to interpret graphs of functions, including cubic, reciprocal and absolute value functions, and to solve equations graphically.
除二次式外，大纲也涵盖求解一个方程为线性、另一个为非线性的联立方程组，非线性方程常涉及圆或抛物线。代入法是关键。你还必须能够解读函数图像，包括三次函数、倒数函数和绝对值函数图像，并能用图像法求解方程。
Modulus equations and inequalities of the form |ax + b| = c or |ax + b| < d require you to consider both positive and negative cases. Graphical approaches help visualise the solutions. In addition, you should be able to transform graphs using translations, reflections and stretches, and to find the equations of transformed curves.
形如 |ax + b| = c 或 |ax + b| < d 的绝对值方程和不等式要求你考虑正、负两种情形。图像法有助于直观显示解集。此外，你应能运用平移、反射和伸缩变换图像，并求出变换后曲线的方程。
5. Indices, Surds and Logarithms | 指数、根式与对数
Fluency with the laws of indices, including fractional and negative exponents, is assumed. You must simplify expressions involving surds, rationalise denominators such as 1/(√a + √b) and solve equations where the unknown appears in a power, e.g. 3^(2x) = 27. The link between indices and logarithms is fundamental.
课程预设你已能熟练运用指数律，包括分数指数和负指数。你必须化简含有根式的表达式，将形如 1/(√a + √b) 的分母有理化，并求解未知数出现在指数中的方程，例如 3^(2x) = 27。指数与对数之间的联系是基础。
Logarithms are introduced as the inverse of exponentiation. Key rules such as logₐ (xy) = logₐ x + logₐ y, logₐ (x/y) = logₐ x – logₐ y and logₐ (xⁿ) = n logₐ x are tested extensively. You must be able to solve logarithmic equations, change the base using logₐ b = log_c b / log_c a, and apply logarithms to real-world growth and decay models.
对数作为指数的逆运算引入。重要法则如 logₐ (xy) = logₐ x + logₐ y、logₐ (x/y) = logₐ x – logₐ y 以及 logₐ (xⁿ) = n logₐ x 被广泛考查。你必须能够解对数方程，利用换底公式 logₐ b = log_c b / log_c a，并将对数应用于现实世界中的增长与衰减模型。
y = aˣ ⇔ x = logₐ y
6. Coordinate Geometry of Straight Lines and Circles | 直线与圆的坐标几何
Coordinate geometry builds on IGCSE Mathematics by adding the equation of a circle. The standard form (x – a)² + (y – b)² = r² describes a circle with centre (a, b) and radius r. You must be able to complete the square to find the centre and radius from a general equation x² + y² + 2gx + 2fy + c = 0, where the centre is (-g, -f) and radius = √(g² + f² – c).
坐标几何在 IGCSE 数学基础上增加了圆的方程。标准形式 (x – a)² + (y – b)² = r² 描述圆心为 (a, b)、半径为 r 的圆。你必须会使用配方法，由一般方程 x² + y² + 2gx + 2fy + c = 0 求出圆心 (-g, -f) 和半径 √(g² + f² – c)。
Finding the equation of a tangent to a circle at a given point involves using the fact that the radius is perpendicular to the tangent. You will also work with the distance between two points, midpoint, and gradient of a straight line, extending to conditions for parallel and perpendicular lines. Intersection of a line and a circle is a common exam problem.
求圆上给定点处的切线方程，需运用半径垂直于切线这一性质。你还需要运用两点间距离、中点和直线斜率，并拓展到平行与垂直条件。直线与圆的交点是常见的考题。
7. Trigonometry | 三角学
The syllabus significantly deepens trigonometric knowledge. You are expected to work in both degrees and radians, and to know exact values for sin, cos and tan of 0°, 30°, 45°, 60° and 90° and their radian equivalents. The graphs of y = sin x, y = cos x and y = tan x must be sketched, and transformations applied to them.
大纲在很大程度深化了三角学知识。你需要同时使用度数和弧度，并熟记 0°、30°、45°、60° 和 90° 及其弧度对应值的 sin、cos、tan 的精确值。必须能画出 y = sin x、y = cos x 和 y = tan x 的图像，并对其进行变换。
Trigonometric identities such as sin²θ + cos²θ = 1 and tanθ = sinθ/cosθ are essential tools for solving equations. More advanced identities like sec²θ = 1 + tan²θ and cosec²θ = 1 + cot²θ may also be required, depending on the depth of the syllabus update. You will solve trigonometric equations within given intervals, often using factorisation or quadratic methods.
三角恒等式如 sin²θ + cos²θ = 1 和 tanθ = sinθ/cosθ 是解方程的关键工具。更复杂的恒等式如 sec²θ = 1 + tan²θ 和 cosec²θ = 1 + cot²θ 也可能被要求，取决于大纲版本。你将在给定区间内求解三角方程，常需运用因式分解或二次方程的方法。
sin²θ + cos²θ = 1
8. Binomial Theorem | 二项式定理
The binomial expansion for a positive integer power n gives (a + b)ⁿ = aⁿ + ⁿC₁ aⁿ⁻¹ b + ⁿC₂ aⁿ⁻² b² + … + bⁿ. The notation ⁿCᵣ or C(n, r) represents the binomial coefficient, and you can calculate it using nCr = n!/(r!(n-r)!) or via Pascal’s triangle. The syllabus often asks to find a specific term, say the term independent of x.
对于正整数幂 n 的二项展开式为 (a + b)ⁿ = aⁿ + ⁿC₁ aⁿ⁻¹ b + ⁿC₂ aⁿ⁻² b² + … + bⁿ。记号 ⁿCᵣ 或 C(n, r) 表示二项式系数，你可以使用 nCr = n!/(r!(n-r)!) 或帕斯卡三角形来计算。大纲常要求找出特定项，比如与 x 无关的项。
When the binomial is expressed as (1 + x)ⁿ, the expansion is 1 + nx + n(n-1)/2! x² + … . Understanding the pattern and being able to state the term in x^r is important. Problems may involve applying the binomial theorem to approximate calculations, such as (1.02)⁵.
当二项式写作 (1 + x)ⁿ 时，展开式为 1 + nx + n(n-1)/2! x² + … 。理解其规律并能写出含 x^r 的项很重要。题目可能涉及应用二项式定理进行近似计算，如 (1.02)⁵。
9. Vectors in Two Dimensions | 二维向量
Vectors are presented as directed line segments and in column form. You need to add and subtract vectors, multiply a vector by a scalar, and calculate the magnitude |v| = √(x² + y²). The unit vector in a given direction is v/|v|. Position vectors and the relationship AB = OB – OA are tested.
向量以有向线段和列向量形式呈现。你需要进行向量加减、标量乘法，并计算模长 |v| = √(x² + y²)。给定方向的单位向量为 v/|v|。位置向量以及 AB = OB – OA 的关系均会考查。
You will also use vectors to solve geometric problems, including proving that points are collinear (vectors are parallel) or finding the ratio in which a point divides a line segment. Interpreting vector paths in shapes such as triangles and parallelograms is a common skill.
你还将运用向量解决几何问题，包括证明点共线（向量平行）或求点分割线段的比例。在三角形和平行四边形等图形中分析向量路径是一项常见技能。
If AB = k BC, then A, B and C are collinear.
10. Differentiation | 微分
Differentiation is introduced as a method for finding gradients of curves and rates of change. The derivative of xⁿ is n xⁿ⁻¹, and this rule applies to sums and differences of terms. You must learn to differentiate polynomial, reciprocal, square root and simple rational functions. The notation dy/dx and f'(x) are both used.
微分作为一种求曲线梯度和变化率的方法引入。xⁿ 的导数为 n xⁿ⁻¹，该法则适用于各项的和与差。你必须学会对多项式、倒数、平方根及简单有理函数进行微分。dy/dx 和 f'(x) 两种记法均被使用。
The syllabus requires the product rule d/dx(uv) = u dv/dx + v du/dx, the quotient rule d/dx(u/v) = (v du/dx – u dv/dx)/v², and the chain rule dy/dx = dy/du × du/dx. Applications include finding equations of tangents and normals to curves, stationary points, and determining whether a stationary point is a maximum or minimum using the second derivative d²y/dx². You will also solve problems concerning connected rates of change.
大纲要求掌握乘积法则 d/dx(uv) = u dv/dx + v du/dx、商法则 d/dx(u/v) = (v du/dx – u dv/dx)/v² 以及链式法则 dy/dx = dy/du × du/dx。应用包括求曲线的切线和法线方程、驻点，以及利用二阶导数 d²y/dx² 判断驻点是极大值还是极小值。你还将解决相关变化率问题。
d/dx (xⁿ) = n xⁿ⁻¹
11. Integration | 积分
Integration is treated as the reverse process of differentiation. The indefinite integral of xⁿ is (xⁿ⁺¹)/(n+1) + c, for n ≠ -1. You must integrate polynomial, negative power and fractional power functions, and find the constant of integration c using given conditions.
积分被视为微分的逆过程。xⁿ 的不定积分为 (xⁿ⁺¹)/(n+1) + c，其中 n ≠ -1。你必须对多项式、负指数和分数指数函数进行积分，并利用给定条件求出积分常数 c。
Definite integrals are calculated and used to find the area under a curve between two limits. The area between a curve and the x-axis from x = a to x = b is ∫ₐᵇ y dx. You will also find areas bounded by a curve and a straight line, requiring the subtraction of areas. Questions often combine differentiation and integration, such as finding the equation of a curve given its derivative and a point.
定积分的计算用于求曲线在两点之间的下方面积。曲线与 x 轴在 x = a 至 x = b 之间的面积为 ∫ₐᵇ y dx。你还将求曲线与直线围成的区域面积，这需要将面积相减。题目常将微分与积分结合起来，比如给定导数和一个点求曲线方程。
∫ xⁿ dx = (xⁿ⁺¹)/(n+1) + c, n ≠ -1
12. Exam Strategies and Common Pitfalls | 考试策略与常见误区
Success in IGCSE Additional Mathematics is built on consistent practice and strategic examination technique. Always start a question by identifying the topics involved, as many problems are multi-concept. Show all working clearly to gain method marks even if the final answer is incorrect. In both papers, about 30% of the marks are allocated to applications and problem solving, so practice unfamiliar contexts regularly.
在 IGCSE 进阶数学中取得成功，离不开持续练习与策略性考试技巧。解题时首先要识别出涉及的主题，因为许多问题都综合多个概念。清晰地展示所有过程，即使最终答案有误，也能获得方法分。两份试卷中约 30% 的分值分配给应用与解决问题，因此请定期练习陌生情境。
Common student errors include forgetting to check the domain for inverse functions, mixing up the chain rule order, missing the constant of integration, and dropping sign errors when solving modulus equations. Always double-check your solutions by substituting back or using alternative methods. Time allotment: aim for roughly 1.5 minutes per mark. With 80 marks in 120 minutes, pacing is tight; leave time to review flagged questions.
常见的考生错误包括：忘记检查反函数的定义域、混淆链式法则的次序、漏掉积分常数以及在解绝对值方程时丢失符号。务必通过回代或使用替代方法复核答案。时间分配：目标约为每分 1.5 分钟。120 分钟内完成 80 分，时间紧凑；请留出时间检查标记的题目。
Past paper practice under timed conditions is the most effective revision tool. Keep a formula sheet of common trigonometry identities, differentiation rules and integration shortcuts for quick recall. With disciplined preparation, you can confidently tackle the breadth of the Additional Mathematics syllabus and achieve the grade you deserve.
限时刷历年真题是最有效的复习工具。汇总一份包含常用三角恒等式、微分法则和积分快捷方式的公式表以便快速回忆。通过严格备考，你定能自信地应对进阶数学大纲的广度，获得应有的成绩。
