- Calculating tolerance and rounding to a given number of significant figures in measurement contexts.
- 在测量情境中计算容差并按指定有效数字进行舍入。
3. Expressions and Formulae | 表达式与公式
This unit focuses on algebraic manipulation: expanding brackets, factorising common factors and difference of two squares, and simplifying surds and expressions involving integer indices. Learners also substitute numbers into formulae, change the subject of a formula, and work with equations of straight lines and linear inequalities.
本单元侧重于代数运算：展开括号、提取公因式与平方差因式分解、简化根式及含整数指数的表达式。学生还将进行公式代入、转换公式主项，并处理直线方程和线性不等式。
Key skills include evaluating an expression like 3(2x − 5) + 4x to 10x − 15, and solving inequalities such as 5 − 2x > 1, giving x < 2. Pupils also practise factorising 4y² − 25 into (2y − 5)(2y + 5).
核心技能包括将表达式 3(2x − 5) + 4x 简化为 10x − 15，并求解不等式 5 − 2x > 1，得出 x < 2。学生也会练习将 4y² − 25 分解为 (2y − 5)(2y + 5)。
4. Relationships and Algebra | 关系与代数
Building on earlier work, this strand introduces linear, quadratic, and simple trigonometric relationships. Students solve quadratic equations by factorising and using the quadratic formula, determine equations of straight lines from two points, and interpret real‑life graphs such as distance‑time and velocity‑time charts.
本模块在前序内容基础上引入线性、二次函数及简单的三角函数关系。学生通过因式分解和求根公式解二次方程，根据两点确定直线方程，并解读距离‑时间图、速度‑时间图等实际关系图。
ts and turning points of parabolas such as y = x² − 4x + 3, with roots at x = 1 and x = 3.
例如，给出两点 (1, 3) 和 (4, 9)，学生计算出斜率 m = 2 及方程 y = 2x + 1。他们还会识别抛物线 y = x² − 4x + 3 的根（x = 1 和 x = 3）与顶点。
5. Geometry and Shape | 几何与图形
Candidates extend their knowledge of 2D shapes and 3D solids by calculating arc length, sector area, and volumes of composite solids. Pythagoras’ theorem and trigonometric ratios in right‑angled triangles are core, along with properties of circles (tangent, chord, angle in a semicircle) and angle facts in parallel lines and polygons.
学生通过计算弧长、扇形面积及组合立体体积来拓展对二维图形与三维体的认识。直角三角形的勾股定理和三角比是核心内容，同时涉及圆的性质（切线、弦、半圆上的圆周角）以及平行线与多边形的角的关系。
A typical problem might ask: 'A sector has radius 6 cm and angle 50°. Find its area.' The solution uses area = (θ/360) × πr², giving (50/360) × π × 36 ≈ 15.7 cm².
典型题目如：“一个扇形半径为 6 cm，圆心角 50°，求其面积。”解法利用面积 = (θ/360) × πr²，得 (50/360) × π × 36 ≈ 15.7 cm²。
6. Statistics and Probability | 统计与概率
The statistics component covers data collection, sampling methods, and the calculation of mean, median, mode, range, interquartile range, and standard deviation. Graphical representation includes dot plots, boxplots, histograms, and scatter graphs, with attention to correlation and line of best fit.
统计部分涵盖数据收集、抽样方法，以及平均值、中位数、众数、极差、四分位距和标准差的计算。图形表示包括点图、箱形图、直方图和散点图，并关注相关性与最佳拟合线。
In probability, learners use tree diagrams and Venn diagrams for combined events, understanding mutually exclusive and independent events. They also calculate expected frequency from probability. For instance, the probability of rolling two sixes with two dice is 1/36, so in 180 trials the expected count is 5.
在概率领域，学生使用树状图和维恩图处理组合事件，理解互斥事件和独立事件。他们还会根据概率计算期望次数。例如，掷两粒骰子均为六点的概率为 1/36，因此在 180 次试验中期望出现 5 次。
7. Trigonometric Skills | 三角学技能
Beyond right‑angled trigonometry, the syllabus introduces the sine and cosine rules for non‑right‑angled triangles, along with the area formula ½ab sin C. Learners apply these to solve bearings, navigation, and surveying problems, and they also begin to work with exact values for sin, cos, and tan of 0°, 30°, 45°, 60°, and 90°.
在直角三角形三角比之外，大纲还引入了用于非直角三角形的正弦定理和余弦定理，以及面积公式 ½ab sin C。学生将这些知识应用于方位角、导航和测量问题中，并开始接触 0°、30°、45°、60° 与 90° 角的正弦、余弦、正切的精确值。
units. The sine rule: a/sin A = b/sin B = c/sin C is used to find missing sides or angles.
对于一个边长为 a=8、b=6，夹角 C=40° 的三角形，面积约为 ½ × 8 × 6 × sin 40° ≈ 15.4 平方单位。利用正弦定理 a/sin A = b/sin B = c/sin C 可求出缺失的边或角。
8. Algebraic Manipulation and Equations | 代数运算与方程
algebraic fractions. Candidates are expected to solve linear equations, inequations, and simple quadratic equations by factorising and using the quadratic formula x = [−b ± √b² − 4ac] / 2a.

They also learn to interpret the discriminant b² − 4ac to determine the nature of roots: two distinct real roots, one repeated root, or no real roots. Problems may include forming an equation from a word problem, e.g. 'The product of two consecutive numbers is 56; find the numbers.'
他们还将学习通过判别式 b² − 4ac 判断根的性质：两个不同实根、一个重根或无实根。题目可能包含根据文字题建立方程，例如“两个连续整数的乘积是 56，求这两个数”。
9. Gradient, Straight Line and Functions | 斜率、直线与函数
formula m = (y₂ − y₁)/(x₂ − x₁) and the equation y − b = m(x − a). They interpret straight‑e graphs in the form y = mx + c, find parallel and perpendicular lines, and identify the x‑ and y‑intercepts. Simple function notation f(x) is used alongside inputs and outputs.
学生巩固了斜率公式 m = (y₂ − y₁)/(x₂ − x₁) 及直线方程 y − b = m(x − a)。他们解读 y = mx + c 形式的直线图，求出平行线与垂直线，并确定 x 轴与 y 轴截距。简单的函数记号 f(x) 以及输入、输出概念也将并行使用。
dicular is −1/3, so the equation is y − 5 = −1/3 (x − 4), which simplifies to 3y + x = 19.
示例：求过点 (4, 5) 且与直线 y = 3x + 2 垂直的直线方程。垂直线的斜率为 −1/3，因此方程为 y − 5 = −1/3 (x − 4)，化简后得 3y + x = 19。
10. Simultaneous Equations and Quadratic Functions | 联立方程与二次函数
Pupils solve pairs of simultaneous equations – both linear/linear and linear/quadratic – by substitution and elimination. Graphical solutions are used to confirm the intersection points of a line and a parabola. They also sketch quadratic functions, identifying roots, axis of symmetry, and maximum/minimum turning points.
学生通过代入法与消元法求解联立方程组（包括线性/线性以及线性/二次方程组）。图形解法用于确认直线与抛物线的交点。他们还会绘制二次函数草图，识别根、对称轴和最大/最小顶点。
or 3, and corresponding y values −1 and 3. The intersection points are (1, −1) and (3, 3).
例如，解方程组 y = x² − 2x 与 y = 2x − 3，得到 x² − 4x + 3 = 0，即 x = 1 或 3，对应的 y 值为 −1 和 3。交点坐标为 (1, −1) 和 (3, 3)。
11. Trigonometric Graphs and Identities | 三角函数图像与恒等式
, and they relate the graphs to solving trigonometric equations like sin x = 0.5 or 3 cos x − 1 = 0 for 0° ≤ x ≤ 360°.
课程引入了以角度为单位的 y = sin x、y = cos x 和 y = tan x 的基本图像。学生描述振幅、周期与关键点，并将图像与解三角函数方程（如 sin x = 0.5 或 3 cos x − 1 = 0，在 0° ≤ x ≤ 360° 范围内）联系起来。
d to simplify expressions. These foundational ideas prepare students for the study of wave functions at Higher level.
此外，还会证明并运用恒等式 sin² x + cos² x = 1，以及 tan x = sin x / cos x 的关系来化简表达式。这些基础概念为学生升入 Higher 阶段学习波动函数做好准备。
12. Assessment and Exam Preparation | 评估与备考
The final assessment comprises two question papers: Paper 1 (non‑calculator) and Paper 2 (calculator), each contributing to a scaled mark total. The course also formerly included an internally assessed Added Value Unit (AVU), which now may be replaced by a portfolio task in some school‑based arrangements. Effective revision integrates timed practice, problem‑solving with real‑world contexts, and systematic review of common pitfalls such as unit consistency and rounding errors.
最终评估包含两份试卷：试卷一（不可使用计算器）和试卷二（可使用计算器），各自按比例计入总分。此前课程还包括内部评估的“增值单元”，在部分学校的安排中可能被项目式作业替代。高效复习应融合限时训练、真实情境的问题解决，以及系统性回顾常见错误，如单位一致性和舍入误差。
| Component | 组件 | Time | 时间 | Marks | 分值 |
|---|---|---|---|---|---|
| Paper 1 (Non‑calculator) | 试卷一（无计算器） | 1 hr 30 min | 1小时30分钟 | 50 | |
| Paper 2 (Calculator) | 试卷二（允许计算器） | 2 hr | 2小时 | 70 |
By mastering the full range of topics – from surds and quadratics to trigonometry and statistics – learners gain confidence in constructing reasoned solutions. This comprehensive approach mirrors the ethos of the SQA Advanced Mathematics syllabus, ensuring readiness for further study and everyday quantitative literacy.
通过掌握从根式、二次方程到三角学和统计学的所有主题，学习者能够自信地构建有理有据的解答。这一全面的学习方式呼应了SQA进阶数学大纲的核心理念，确保学生为后续学习和日常量化素养做好准备。
