How to use the solutions

Mark your own work like an examiner

Each solution is written as an IB mark scheme: M1 for a method mark, A1 for an answer mark that depends on the method, R1 for reasoning and AG where the answer is given in the question. Where your method differs, check that each of your lines would earn the same marks.

The questions are in Photon Guidebook: Mathematics Applications and Interpretation SL for the IB Diploma, available as an e-book in one volume. The book gives calculator keystrokes for the TI-Nspire CX II and the Casio fx-CG50.
