2. How IB Students Can Use an Edexcel Further Maths Guide | IB 学生如何利用 Edexcel 进阶数学指南
IB Higher Level Mathematics: Analysis and Approaches and Applications and Interpretation share many topics with Edexcel Further Maths, such as complex numbers, proof by induction, matrices, vectors, and differential equations. IB students can use the CGP book as a supplementary revision bank, but should note differences in notation and emphasis, especially in statistics where IB uses t-distributions and Poisson distributions differently.
IB 高级数学：分析与方法、应用与解释与 Edexcel 进阶数学共享许多主题，如复数、归纳法证明、矩阵、向量和微分方程。IB 学生可以把此书作为补充复习题库，但应注意符号和重点差异，特别是在统计学中，IB 对 t 分布和泊松分布的处理有所不同。
One advantage of this resource is that every topic is broken into small chunks with clear methods. IB students can use the chapters on Core Pure to build speed, while treating the mechanics and statistics sections as optional extension material.
该资源的一个优势是每个主题都被分解成小块并配以清晰方法。IB 学生可以利用核心纯数学章节提升解题速度，同时将力学和统计部分作为可选拓展材料。
Be careful with terminology: Edexcel often says 'argument' for the angle of a complex number, whereas IB exam papers may phrase the same idea as 'principal argument'. Checking the specification glossary reduces confusion.
注意术语差异：Edexcel 常用 'argument' 表示复数的辐角，而 IB 试卷可能将同一概念表述为 'principal argument'。检查大纲术语表可以减少混淆。
3. Core Pure Mathematics: Complex Numbers | 核心纯数学：复数
njugates, and represent them on an Argand diagram. Solving quadratic and cubic equations with complex roots is a frequently examined skill.
复数是核心纯数学 1 的核心内容。你必须能对 z = a + bi 形式的数进行加、减、乘、除，求共轭复数，并在 Argand 图上表示它们。求解具有复数根的二次方程和三次方程是常见考点。
z = a + bi, z̄ = a − bi, |z| = √a² + b²
Worked practice should include de Moivre' m, converting between rectangular and modulus-argument form, and interpreting loci such as |z − w| = r as a circle.
练习应包括棣莫弗定理、直角坐标形式与模辐角形式之间的转换，以及将 |z − w| = r 等轨迹解释为圆。
Use the CGP worked examples to practise finding roots of unity and showing geometric properties on an Argand diagram. Always state the modulus and argument clearly before applying de Moivre's theorem.
利用 CGP 例题练习求单位根，并在 Argand 图上展示几何性质。在应用棣莫弗定理前，始终清晰地写出模和辐角。
4. Matrices and Linear Transformations | 矩阵与线性变换
atrices, and understand invariant lines, invariant points, and successive transformations.
矩阵用于表示二维和三维空间中的线性变换。你需要计算 2 × 2 和 3 × 3 矩阵的行列式和逆矩阵，并理解不变直线、不变点以及连续变换。
For A = [[a, b], [c, d]], det(A) = ad − bc, A⁻¹ = 1/det(A) [[d, −b], [−c, a]]
nt as an area scale factor and on finding eigenvalues and eigenvectors for 2 × 2 matrices.
CGP 书中有关于行列式作为面积比例因子以及求 2 × 2 矩阵特征值和特征向量的例题。
When dealing with successive transformations, remember that the first transformation is written on the right of the product. For example, transformation A followed by B is represented by BA, not AB.
处理连续变换时，记住第一个变换写在乘积的右边。例如，先进行变换 A 再进行变换 B 表示为 BA，而不是 AB。
5. Further Calculus | 进阶微积分
Further Calculus covers reduction formulae, arc length, surface area of revolution, and differentiation of inverse trigonometric functions. Questions often require repeated integration by parts and careful limits.
进阶微积分涵盖递推公式、弧长、旋转曲面面积以及反三角函数的微分。题目通常要求反复使用分部积分并仔细处理积分限。
∫ u dv = uv − ∫ v du, ∫ xⁿ dx = xⁿ⁺¹/(n + 1) + C (n ≠ −1)
t for standard integrals and shows how to set up a reduction formula for Iₙ = ∫ sinⁿ x dx.
《完整复习与练习》为标准积分提供了复习清单，并展示了如何为 Iₙ = ∫ sinⁿ x dx 建立递推公式。
For arc length and surface area problems, set up the integral in the correct form before trying to evaluate it. Many students lose marks by using the wrong limits or forgetting the squared derivative inside the square root.
对于弧长和曲面面积问题，在尝试求值之前先建立正确形式的积分。许多学生因使用错误积分限或忘记根号内导数需要平方而失分。
6. Hyperbolic Functions | 双曲函数
Hyperbolic functions sinh x, cosh x, and tanh x are defined through exponentials and appear in Core Pure 2. You need their graphs, inverse functions, and identities, including the Osborne rule for analogies with trigonometric identities.
双曲函数 sinh x、cosh x 和 tanh x 通过指数定义，并出现在核心纯数学 2 中。你需要掌握它们的图像、反函数以及恒等式，包括与三角恒等式类比的 Osborne 规则。
cosh² x − sinh² x = 1, sinh x = (eˣ − e⁻ˣ)/2, cosh x = (eˣ + e⁻ˣ)/2
Practice questions often ask you to solve equations involving hyperbolic functions by converting to exponential form or using identities to obtain quadratic equations.
练习常要求通过转换为指数形式或利用恒等式得到二次方程，来求解含双曲函数的方程。
Pay close attention to the inverse hyperbolic functions arsinh x, arcosh x, and artanh x. Their logarithmic forms are given in the formula book, but you must know which domain each inverse function requires.
特别注意反双曲函数 arsinh x、arcosh x 和 artanh x。它们的对数形式在公式手册中给出，但你必须清楚每个反函数所需的定义域。
7. Differential Equations | 微分方程
First-order and second-order differential equations are a major part of Further Maths. You must solve separable equations, use integrating factors, and find general and particular solutions. For second-order linear equations with constant coefficients, the auxiliary equation determines the complementary function.
一阶和二阶微分方程是进阶数学的重要组成部分。你必须会解可分离变量方程、使用积分因子，并求出通解和特解。对于常系数二阶线性微分方程，辅助方程决定余函数。
For ay″ + by′ + cy = 0, auxiliary equation: am² + bm + c = 0
The CGP revision guide emphasizes checking the form of a particular integral, especially when the right-hand side is polynomial, exponential, or trigonometric.
CGP 复习指南强调检查特解积分的形式，特别是当右端为多项式、指数函数或三角函数时。
y the whole differential equation by it. Remember that the left-hand side becomes the derivative of a product, which makes the equation directly integrable.
当需要积分因子时，将其写为 e^∫ P(x) dx 并与整个微分方程相乘。记住此时左侧变为某个乘积的导数，从而使方程可以直接积分。
8. Further Mechanics and Momentum | 进阶力学与动量
Further Mechanics 1 extends M1 and M2 ideas to impulse, conservation of momentum, elastic collisions, and work-energy principles. You must be confident with vector notation for velocity and impulse in two dimensions.
进阶力学 1 将 M1 和 M2 的概念拓展到冲量、动量守恒、弹性碰撞和功能原理。你必须熟练使用二维速度和冲量的向量记法。
Impulse = m(v − u), Momentum = mv, e = speed of separation / speed of approach
When using the book, pay attention to questions that combine momentum with energy conservation and with constant acceleration equations.
使用本书时，要特别注意将动量与能量守恒以及匀加速运动方程相结合的题目。
Always define a positive direction before writing momentum equations. In two-dimensional collision problems, resolve into perpendicular components and apply conservation laws separately in each direction.
在写动量方程前，始终先定义正方向。在二维碰撞问题中，将运动分解为垂直分量，并在每个方向上分别应用守恒定律。
9. Further Statistics and Discrete Random Variables | 进阶统计与离散随机变量
Further Statistics 1 extends discrete random variables, Poisson distribution, Chi-squared tests, and geometric and negative binomial distributions. Expect questions that require calculating probabilities using probability generating functions.
进阶统计 1 拓展离散随机变量、泊松分布、卡方检验、几何分布和负二项分布。考试可能出现要求使用概率生成函数计算概率的题目。
E(X) = Σ x P(X = x), Var(X) = E(X²) − [E(X)]², Poisson: P(X = r) = e⁻λ λʳ / r!
The CGP book includes model answers for hypothesis tests and for using contingency tables with degrees of freedom (rows − 1)(columns − 1).
CGP 书中有关于假设检验和使用列联表的模型答案，自由度为 (行数 − 1)(列数 − 1)。
′(1)]². Always check that the probabilities sum to 1 before calculating these derivatives.
使用概率生成函数时，记住 E(X) = G′(1) 且 Var(X) = G″(1) + G′(1) − [G′(1)]²。在计算这些导数前，始终检查概率之和是否为 1。
10. Decision Mathematics 1 Highlights | 决策数学 1 重点
If your centre offers Decision Mathematics 1, the CGP book covers algorithms such as Dijkstra, Kruskal, Prim, and the simplex method. You should practise tracing algorithms step by step and interpreting output tables.
如果你的学校开设决策数学 1，CGP 书涵盖 Dijkstra、Kruskal、Prim 和单纯形法等算法。你应练习逐步追踪算法并解读输出表。
Practise drawing activity networks and scheduling diagrams, since these are common in exam papers but easy to lose marks on if labels are omitted.
练习绘制活动网络和调度图，因为它们在试卷中常见，但若漏掉标注很容易失分。
For linear programming problems, identify the objective function and constraints before applying the simplex method. Write each tableau clearly, and state the final
