1. Exam Structure and Assessment | 考试结构与评估
The qualification is linear, meaning all content is assessed at the end of the course through two written papers. Both papers can feature questions from any part of the syllabus, and the use of a calculator is permitted only in Paper 2. The following table summarises the key assessment details.
该资格为线性课程，所有内容在课程结束时通过两份笔试试卷进行评估。两份试卷均可能涵盖大纲任何部分，仅试卷 2 允许使用计算器。下表总结了关键评估信息。
| Component | 组成部分 | Duration | 时长 | Weighting | 权重 | Calculator Allowed? | 是否可用计算器 |
|---|---|---|---|
| Paper 1 | 1 hour 30 minutes | 50% | No |
| Paper 2 | 1 hour 30 minutes | 50% | Yes |
Each paper carries a total of 80 marks, giving an overall maximum of 160 marks. The questions range from structured single-step problems to more extended, multi-part tasks that require clear logical reasoning.
每份试卷满分为 80 分，总共 160 分。题型涵盖从结构化的单步骤问题到需要清晰逻辑推理的较长、多部分任务。
2. Algebra: Manipulation and Factorisation | 代数：运算与因式分解
A strong command of algebraic manipulation is essential for every topic in Further Mathematics. You must be able to expand products of brackets, factorise quadratic and cubic expressions, and simplify rational expressions by cancelling common factors. Techniques such as completing the square are also tested, often linking to graph sketching and solving equations.
扎实的代数运算能力对进阶数学的每一主题都至关重要。你必须能够展开括号乘积，因式分解二次及三次表达式，并通过消去公因式简化有理式。配方法等技巧也常考，通常与画图和方程求解相关联。
For example, completing the square for x² + 6x + 5 yields (x + 3)² - 4, which immediately reveals the vertex of the corresponding parabola. Similarly, factorising a cubic such as x³ - 3x² - 4x + 12 by grouping or using the factor theorem is a core skill. Algebraic fractions are manipulated using common denominators, mirroring numerical fractions but with polynomial numerators and denominators.
例如，对 x² + 6x + 5 进行配方得到 (x + 3)² - 4，它直接揭示了相应抛物线的顶点。类似地，通过分组或因式定理将三次式 x³ - 3x² - 4x + 12 因式分解是一项核心技能。代数分式的运算采用通分，与数字分式相似，只不过分子和分母为多项式。
3. Polynomials and Binomial Expansion | 多项式与二项式展开
f polynomial p(x) if and only if p(a) = 0. This forms the basis for factorising cubics and solving polynomial equations.
多项式在教学大纲中占有重要地位。你需要进行多项式长除法，并运用因式定理：当且仅当 p(a) = 0 时，(x - a) 是多项式 p(x) 的因式。这是因式分解三次式和求解多项式方程的基础。
The binomial expansion is extended to any rational exponent, although for WJEC only positive integer powers appear regularly. The expansion of (a + b)ⁿ follows the pattern involving binomial coefficients (n choose r), written as ⁿCᵣ or (n r). A typical question might ask you to expand (1 + 2x)⁴ using Pascal's triangle or the coefficient formula, and then perhaps to use the expansion to estimate a power such as 1.02⁴.
二项式展开被扩展至任意有理数指数，不过 WJEC 通常只涉及正整数幂。(a + b)ⁿ 的展开遵循含有二项式系数 (n 选 r) 的模式，记作 ⁿCᵣ 或 (n r)。一个典型的题目可能会要求利用帕斯卡三角形或系数公式展开 (1 + 2x)⁴，然后可能利用该展开式估算 1.02⁴ 这样的幂。
(1 + x)ⁿ = 1 + nx + [n(n-1)/2!]x² + ... + xⁿ
4. Coordinate Geometry and Circles | 坐标几何与圆
e centre and r is the radius. You must be able to find the centre and radius by completing the square when the equation is given in expanded form. The relationship between the radius and a tangent is crucial: the tangent at a point is perpendicular to the radius at that point, allowing you to find tangent and normal equations.
在 GCSE 数学的直线学习之外，你将学习圆的标准方程 (x - a)² + (y - b)² = r²，其中 (a, b) 是圆心，r 是半径。当给出的是圆的展开式时，你必须能通过配方法求出圆心和半径。半径与切线之间的关系至关重要：圆上一点的切线垂直于该点处的半径，从而可以求出切线和法线方程。
The discriminant can be used to determine whether a line intersects a circle, is tangent to it, or misses it entirely. Setting the simultaneous equations of a line and circle yields a quadratic; its discriminant tells you the number of intersection points. This algebraic approach is heavily examined.
判别式可用于确定一条直线是与圆相交、相切，还是完全不相交。联立直线与圆的方程会得到一个二次方程，其判别式表明交点的个数。这一代数方法经常考查。
5. Introduction to Calculus | 微积分入门
This topic distinguishes Further Mathematics from standard GCSE Mathematics. You will learn to differentiate simple polynomial functions and use differentiation to find gradients of curves, stationary points, and the nature of maxima and minima. Integration is taught as the reverse process of differentiation, enabling you to find indefinite integrals and evaluate definite integrals to calculate areas under curves.
这一主题将进阶数学与普通 GCSE 数学区分开来。你将学习多项式函数的简单微分，并利用微分求曲线的梯度、驻点以及极大值和极小值的性质。积分作为微分的逆运算进行教学，使你能够求出不定积分并计算定积分以求得曲线下的面积。
ea bounded by the curve y = x² + 1, the x-axis, and the lines x = -1 and x = 2. You set up the definite integral and evaluate it by substituting the limits.
幂法则是根本：若 y = xⁿ，则 dy/dx = nxⁿ⁻¹。对于积分，∫ xⁿ dx = xⁿ⁺¹/(n+1) + C，其中 n ≠ -1。一个典型的应用是求由曲线 y = x² + 1、x 轴以及直线 x = -1 和 x = 2 所围成的面积。你需要建立定积分并代入上下限计算。
dy/dx = limh→0 [f(x+h) - f(x)] / h and d(xⁿ)/dx = n xⁿ⁻¹
6. Matrices | 矩阵
Matrices are introduced as rectangular arrays of numbers that can represent data or geometric transformations. You must be able to add and subtract matrices of the same order, multiply a matrix by a scalar, and multiply two compatible matrices. The order of multiplication matters, since matrix multiplication is not commutative in general.
矩阵被引入为可表示数据或几何变换的矩形数字阵列。你必须能对同阶矩阵进行加减、用标量乘矩阵，并将两个相容的矩阵相乘。相乘的顺序很重要，因为矩阵乘法一般不满足交换律。
idual transformation matrices in the correct order. The determinant of a 2×2 matrix (ad - bc) is used to find the inverse of the matrix, which reverses the transformation. If the determinant is zero, the matrix is singular and has no inverse. You may also need to solve matrix equations of the form AX = B by pre-multiplying by A⁻¹.
一个关键应用是组合变换：将一个反射后接一个旋转可通过按正确顺序相乘各个变换矩阵而用单个矩阵表示。2×2 矩阵的行列式 (ad - bc) 用于求该矩阵的逆，逆矩阵可以逆转变换。如果行列式为零，则该矩阵是奇异矩阵，没有逆。你还需要通过左乘 A⁻¹ 求解形如 AX = B 的矩阵方程。
7. Vectors | 向量
Vectors are used to describe quantities that have both magnitude and direction. You will represent vectors in column form and using i, j notation. Operations include addition, subtraction, and multiplication by a scalar. Calculating the magnitude (length) of a vector using Pythagoras' theorem is a key skill.
向量用于描述既有大小又有方向的量。你将用列向量以及 i, j 表示法表示向量。运算包括加法、减法和标量乘法。运用勾股定理计算向量的模（长度）是一项关键技能。
nce, if AB = k·AC, then points A, B, and C are collinear. Vector methods also solve problems involving parallel lines and shapes in the coordinate plane without relying on coordinate geometry equations.
在几何上，向量有助于证明共线性（点位于同一直线上）并求一点分线段的比例。例如，若 AB = k·AC，则点 A、B 和 C 共线。向量方法还能解决涉及平行线及坐标平面内图形的问题，而不必依赖于坐标几何方程。
8. Functions and Their Graphs | 函数与图像
ons, and inverse functions. You will explore notation such as f(x) = 2x + 3, and find composite functions fg(x) meaning f(g(x)). The inverse function f⁻¹(x) is defined such that ff⁻¹(x) = x, and its graph is the reflection of f(x) in the line y = x.
函数将每个输入恰好映射到一个输出，这一概念在进阶数学中进一步扩展到包括定义域、值域、复合函数和反函数。你将探究如 f(x) = 2x + 3 这样的记法，并求复合函数 fg(x)（即 f(g(x))）。反函数 f⁻¹(x) 定义为满足 ff⁻¹(x) = x，其图像是 f(x) 以直线 y = x 为对称轴的反射。
Graph transformations form a major part of the syllabus. You must understand the effect of applying f(x) + a, f(x + a), -f(x), f(-x), and af(x) to a given graph. These correspond to vertical/horizontal shifts, reflections in the axes, and vertical stretches. Combining transformations and describing the resulting graph analytically is a common examination task.
图像变换构成了大纲的重要部分。你必须理解将一个给定图像应用 f(x) + a、f(x + a)、-f(x)、f(-x) 和 af(x) 的效果。这些对应垂直/水平平移、关于坐标轴的反射以及垂直伸缩。组合变换并解析地描述所得图像是常见的考试任务。
9. Trigonometry and Identities | 三角学与恒等式
size, including their graphs and periodic properties. The unit circle approach helps visualise how sin θ, cos θ, and tan θ vary as θ changes. You need to solve equations such as sin x = 0.5 for 0° ≤ x ≤ 360°, finding all possible solutions using the symmetry of the graphs.
进阶数学中的三角学超越了直角三角形。你将学习任意角的正弦、余弦和正切函数，包括它们的图像和周期性质。单位圆方法有助于可视化当 θ 变化时 sin θ、cos θ 和 tan θ 如何变化。你需要求解 sin x = 0.5 在 0° ≤ x ≤ 360° 区间内的方程，并利用图像的对称性求出所有可能的解。
re complex equations where a mixture of functions appears. For example, substituting sin²θ = 1 - cos²θ can turn an equation into a quadratic in cos θ, which can then be factored.
两个基本恒等式是核心：tan θ = sin θ / cos θ 以及 sin²θ + cos²θ = 1。它们被用于化简三角表达式以及求解出现多种混合函数的更复杂方程。例如，代入 sin²θ = 1 - cos²θ 可将一个方程转化为关于 cos θ 的二次方程，然后可通过因式分解求解。
10. Inequalities, Sequences, and Proof | 不等式、数列与证明
ng. After rearranging to get zero on one side, you sketch the associated parabola to identify where the inequality holds. Solutions are expressed using set notation or number-line intervals. Linear inequalities in two variables define regions on the coordinate plane, and you must be able to shade these regions and find points that satisfy the constraints.
求解如 x² - 3x ≤ 4 的二次不等式需要细心处理。在通过移项使一边为零后，你可以画出对应的抛物线草图以确定不等式成立的区间。解用集合记法或数轴区间表示。含两个变量的一次不等式在坐标平面上界定区域，你必须能够给这些区域涂色并找出满足约束条件的点。
clude using the nth term formula and recurrence relations. You might be given u₁ = 3 and un+1 Although arithmetic and geometric series are more typical of A Level, recognising simple patterns and proving a term value by induction can appear.
数列扩展到包括使用第 n 项公式和递推关系。你可能会遇到 u₁ = 3 且 un+1 = 2u_n + 5 并以此生成项。尽管等差和等比级数更多在 A Level 中出现，识别简单模式并通过归纳法证明项值也可能出现。
Proof is a thread running through the entire syllabus. You will be expected to construct algebraic proofs, such as proving that the sum of three consecutive integers is divisible by 3. Counterexamples are used to disprove a statement, while direct deduction and exhaustion are common methods. These tasks develop logical precision that is invaluable for advanced study.
证明是贯穿整个大纲的一条主线。你将被要求构建代数证明，例如证明三个连续整数之和能被 3 整除。反例被用来证伪一个命题，而直接推导和穷举法是常用的方法。这些任务培养对高阶段学习极有价值的逻辑严谨性。
