📚 IB Formula Booklet Master Guide | IB 公式手册完全指南
The IB formula booklet is an official reference document that candidates may use during externally assessed examinations. It contains the key equations, constants and relationships required by the syllabus, so you do not need to memorise every formula. However, the booklet is subject-specific, and each course has its own version.
IB 公式手册是一份官方参考资料，考生可以在外部评估考试中使用。它包含课程大纲要求的关键方程、常数和关系式，因此你不需要背诵每一个公式。但公式手册按学科划分，每门课程都有自己的版本。
For Mathematics, there are separate booklets for Analysis & Approaches (AA) and Applications & Interpretation (AI). For experimental sciences, the booklets are often called data booklets, for example the Physics data booklet and the Chemistry data booklet. These documents are updated by the IB for each curriculum cycle.
数学学科中，分析与方法（AA）和应用与解释（AI）有各自独立的公式手册。实验科学通常称为数据手册，例如物理数据手册和化学数据手册。IB 会针对每一轮课程更新这些文件。
1. What Is the IB Formula Booklet? | 什么是 IB 公式手册？
The formula booklet is not a cheat sheet but a standardised set of references that all candidates receive. Its purpose is to reduce unnecessary memorisation and allow you to focus on applying concepts, interpreting data and constructing logical solutions.
公式手册不是作弊纸，而是所有考生都会获得的标准化参考资料。它的目的是减少不必要的记忆，让你专注于应用概念、解释数据和构建逻辑解答。
Each subject booklet follows the syllabus structure, so the same equation may appear in both the mathematics and physics booklets. You should always use the booklet provided for your specific course and exam session, not an edited version.
每门学科的手册都遵循课程大纲结构，因此同一个方程可能同时出现在数学和物理手册中。你应当使用针对你课程和考试场次提供的官方版本，而不是自己编辑的版本。
2. Official Booklets by Subject | 各学科官方公式手册
Mathematics AA and AI each have a dedicated formula booklet that is allowed in all written papers. These booklets include algebra, functions, trigonometry, calculus, statistics and probability formulas depending on the course.
数学 AA 和 AI 各有专用公式手册，在所有笔试中均可使用。根据课程不同，手册内容包括代数、函数、三角、微积分、统计和概率公式。
Physics uses a data booklet that includes fundamental constants, unit conversions, and equations organised by topic such as mechanics, thermal physics, waves, electricity and quantum physics.
物理使用数据手册，其中包括基本常数、单位换算以及按主题组织的方程，如力学、热物理、波、电学和量子物理。
Chemistry provides a data booklet with the periodic table, physical constants, bond enthalpies, standard electrode potentials and selected organic chemistry data.
