Sine rule, cosine rule, 3D trigonometry, and graphs of functions.
Before we list the resources, it is crucial to understand why PDF notes have become the gold standard for HKDSE candidates.
You can find a variety of high-quality free and paid DSE Math notes online. Here are some of the most reliable sources:
Not all notes are created equal. When downloading or purchasing DSE Math notes, look for these key elements: Dse Math Notes Pdf
To help tailor this advice further, tell me (e.g., Level 4, Level 5*) or which specific math topic you find most challenging. I can then provide a targeted structural outline or a specialized formula breakdown for that exact area. Share public link
Many star tutors offer free sample notes or summary booklets.
Quickly find specific formulas or topics using the "Ctrl+F" or "Find" function, saving hours of flipping through pages. Sine rule, cosine rule, 3D trigonometry, and graphs
Because they are distributed in PDF format, they are accessible on tablets and laptops, making them perfect for "paperless" revision and last-minute cramming.
Equations of circles and straight lines. 4. Data Handling (Statistics)
| Strand | Key Topics | |--------|-------------| | | Quadratic equations, functions, exponential & logarithmic functions, polynomials, sequences (arithmetic & geometric), inequalities | | Measures, Shape & Space | Congruence & similarity, theorems on circles (e.g., tangent-chord theorem), 2D/3D trigonometry (sine/cosine rules, angle between line and plane), coordinate geometry (equation of straight line, circle, parabola) | | Data Handling | Measures of central tendency (mean, median, mode), dispersion (range, interquartile range, standard deviation), probability (conditional probability, Bayes’ theorem basics), permutation & combination | | Advanced Topics (often in notes) | Linear programming, locus, transformation geometry, applications of matrix (basic) | Here are some of the most reliable sources:
