Trigonometry, Indices & Proportion | KS3 to GCSE Maths Bundle

Prepare pupils for GCSE maths with three KS3 to GCSE workbooks covering right-angled trigonometry, indices and standard form, and direct and inverse proportion.

• Module 23 – Right-Angled Trigonometry. Use SOHCAHTOA to find missing sides and angles, then apply trigonometry to problems involving angles of elevation and depression.
• Module 24 – Indices & Standard Form. Apply index laws, work with zero and negative powers, and convert, compare and order numbers in standard form.
• Module 25 – Direct & Inverse Proportion and Compound Measures. Connect tables, equations and graphs, then apply proportion to speed, density and unit prices.

Includes 253 pages and 56 step-by-step worked examples, with guided and independent practice, assessment tasks, worked answers and mark schemes. All three pupil workbooks and teacher guides come as printable PDFs and editable Word files.
