BetterMath Notes
The notes
Complete course notes for IB Mathematics: Analysis and Approaches HL, to read, download and use in class.
Notes that explain why
Each chapter builds the topic in order, starting from the reason it exists. Formulas from the IB booklet are marked, and every idea comes with a fully worked example.
Your Turn, every section
A practice block closes each section, so you check an idea while it is fresh rather than at the end of the chapter.
Exam-style problems
Chapters end with Paper 1 and Paper 2 style questions, then challenge investigations for anyone who wants to go further.
Look inside
The first pages of Chapter 2
The chapter opens with why the topic matters, then builds each idea with definitions, worked examples and a Your Turn block. Click a page to read the whole chapter.
Chapters
One chapter at a time
Each chapter is its own PDF, with the syllabus points it covers. Higher Level content is marked throughout, so a Standard Level reader can see what to skip.
Found a mistake?
Tell me where it is
Notes this size will contain errors, and the ones a reader finds are worth more than the ones I go looking for. If a line does not follow, an answer looks wrong, or a passage is hard to read, please say so and I will fix it in the next release.
