Every worksheet question worked in full.
A complete 26-page IGCSE guide to right-angled trigonometry. It starts with labelling the opposite, adjacent and hypotenuse, then teaches SOH CAH TOA for finding missing sides and missing angles. It also covers the exact values for 0°, 30°, 45°, 60° and 90°, and shows how to derive them from two special triangles. Later sections apply trigonometry to angles of elevation and depression, bearings, isosceles triangles, rhombuses and 3D problems with cuboids and pyramids. A final section explains how to choose between Pythagoras and trigonometry. Every method comes with clear diagrams and step-by-step worked examples. It ends with a summary, a keyword guide and exam tips.
