What examiners said
Most proofs were complete. The best solutions stated that r ≠ 0 before dividing.
— Examiner report, October/November 2023, 9231/11 Q6(a) (Cambridge)
The majority of candidates found the result θ = π6 . For a complete solution the possibility that cosθ = 0 should have been considered. Candidates are reminded to express polar coordinates in the form (r ,θ )
— Examiner report, October/November 2023, 9231/11 Q6(b) (Cambridge)
Most diagrams were of acceptable shape and labelled correctly. Good sketches clearly showed C1 as a semi-circle with P on the right-hand side of C1 .
