4 resourcesTrig Identity Proofs
Prove identities using sin²θ + cos²θ ≡ 1 and tan θ ≡ sin θ / cos θ: one-, two-, three- and four-step proofs, each step with its reason, then decide whether a statement is always, sometimes or never true and explain why. Five…
🧩 ConnectionsSimplifying Trig (sin, cos, tan)
Sixteen expressions in sin x, cos x and tan x: find the four that simplify to the same thing, using tan x = sin x ÷ cos x and sin²x + cos²x = 1.

Blockbusters with the questions from the Trig Identity Proofs worksheet: choose its levels for the ordinary hexagons and for the harder ★ ones. Show the answer and the worked solution, or play against the computer with multiple…
🧮 ToolVisual Proofs
Animated visual proofs of Pythagoras’ theorem, of the sums of integers, odd numbers, squares and cubes, and of key results in algebra, geometric series, trigonometry and inequalities. They play like Shape Formulas: drag the bar…
These are the pages for Trigonometric identities in the GCSE + AQA Level 2 Further Maths scheme of work, following Pearson Edexcel GCSE (9–1) Higher (1MA1), plus AQA Level 2 Further Mathematics (8365). Open this topic in Mr Wells Maths to see it alongside the rest of the course.
