Analysis and Approaches book. Neutron rest mass 𝑚n1675 1027 kg 1008665 u 940 MeV c2. So as far as I know there were no changes since 2014 and hence you can use Maths HL Data Booklet for 2014 I think Data Booklet for 2016 does not even exist.
I did exams in 2015 and I used 2014 Data Booklet as well.
For use during the course and in the examinations. Functions SL and HL 5 HL only 5 Topic 3. So it is fine. For use during the course and in the examinations.
