Pure 3: Trigonometric Formulae

A free trigonometric formulae worksheet for A-Level and International A-Level Maths, covering the trigonometric formulae content of Pure Mathematics 3. It works through labelling sides and the three ratios, finding a missing angle and exact values, elevation and depression. Questions are grouped into fluency, reasoning and problem solving, so you build the technique first and then apply it to the kind of unfamiliar, multi-step questions that separate grades in the exam. Written to match the style and presentation of Edexcel International A-Level and 9MA0. Full step-by-step solutions are provided in a separate PDF, so you can check your method as well as your answer.
