 Discrete mathematics, continuous mathematics, and probability resit examination by the University of Oxford (2015)

Primary source: released examination archive, member a10100w1-4.pdf. The original eleven-page cover identifies the Preliminary Examination in Computer Science, Long Vacation 2015, Wednesday 9 September. The archive folder name is not the examination year. Page 8, Question 6(b)(iii), explicitly identifies “saddle point” with “point of inflexion”; that usage is specific to this paper. The definition in Question 6(a)(ii) leaves endpoint values unspecified, which does not affect its Fourier series.
