Exact Trigonometric Values | OCR GCSE Maths Higher | 40 Worked Examples (J560)

Exact trigonometric values for OCR GCSE (9-1) Mathematics Higher tier (J560). 40 exam-style questions with fully worked, mark-scheme-annotated solutions: the exact values of sin, cos and tan at 0, 30, 45, 60 and 90 degrees, where they come from (the two special triangles), and how to apply them without a calculator. Covers finding exact sides and areas in right-angled triangles, area of a triangle with half-ab-sin-C, the sine and cosine rules with special angles, solving trig equations across 0 to 360 degrees by symmetry, and surd ‘show that’ proofs. Progressive Easy to Challenging difficulty. Every working line is annotated, with OCR M/A/B marks folded in on the real mark-scheme lines. Built for OCR’s no-formula-sheet exam: these values are a non-calculator skill on paper J560/05 and must be recalled from memory, so the pack opens with the values table and the two triangles that generate it. Matches spec statement 10.05c and is calibrated against OCR J560 past papers and mark schemes, not ported from another board. Ideal for revision, homework, and 1-1 tuition.
