Year 12 OCR Mathematics covers a broad range of pure and applied topics, building on GCSE knowledge and forming the foundation for the full A Level. This article reviews the core content areas, including algebra, functions, coordinate geometry, trigonometry, calculus, vectors, statistics and mechanics. Understanding these concepts is essential for success in both AS and A Level examinations.

OCR 12年级数学涵盖了广泛的纯数与运用内容，在GCSE基础上发展，并为完整的A Level建立基础。本文梳理核心知识点，包括代数、函数、坐标几何、三角学、微积分、向量、统计学和力学。掌握这些概念对于AS和A Level考试的成功至关重要。

1. Algebraic Fundamentals and Polynomials | 代数基础与多项式

Mastering algebraic manipulation is crucial. You must be confident with the laws of indices, such as aᵐ × aⁿ = aᵐ⁺ⁿ and (aᵐ)ⁿ = aᵐⁿ. You also need to expand brackets, factorise expressions (including quadratics and difference of two squares), and combine polynomials through addition, subtraction and multiplication.

熟练掌握代数运算是关键。你必须熟悉指数律，如 aᵐ × aⁿ = aᵐ⁺ⁿ 和 (aᵐ)ⁿ = aᵐⁿ。你还需要展开括号、因式分解表达式（包括二次式和平方差），以及通过加、减和乘法合并多项式。

Be comfortable simplifying rational expressions by factorising and cancelling common factors. These skills underpin later topics such as calculus and equation solving.

能够通过因式分解和
