Introduction
A free trigonometric identities & equations worksheet for A-Level and International A-Level Maths, covering the trigonometric identities & equations content of Pure Mathematics 2. It works through the identities sin²θ + cos²θ = 1 and tan θ = sin θ ÷ cos θ, solving trigonometric equations in a given interval, equations with multiple angles and quadratic trigonometric equations. Each worksheet opens with worked examples and matching Your turn questions, then moves through fluency, reasoning, problem solving and exam-style practice, with Core and Stretch questions in every section, 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.
