Vectors | OCR A-Level Maths | 40 Worked Examples (H240)

A complete, exam-calibrated worked-solutions pack on Vectors for OCR A-Level Mathematics A (H240), built straight from the OCR specification and past papers. 40 questions ramp from Easy to Challenging: 2D and 3D component form, magnitude, unit vectors, direction from the positive x-axis, position and displacement vectors, distance between points, midpoints, ratio division of a line, parallel and collinear points, and full geometric vector problems on triangles, parallelograms and trapezia, plus resultant-force and kinematics-collision contexts. Every solution is broken down to one atomic step per line with a plain-English explanation, a right-margin note on what each line does, and the real OCR mark-scheme codes (M, A, B, and the B* / B-dep proof marks) folded in on the lines that actually earn them. Includes the classic ‘name the quadrilateral with a reason’ question and a worked kite proof taken to full detail-reasoning standard. Scope is kept strictly to H240: no scalar (dot) product and no vector line equations, and 3D direction is correctly excluded, so students revise exactly what OCR examines and nothing off-spec. Ideal for Paper 1 revision, homework, or one-to-one tuition.
