I tutor Chemistry, Physics and Biology, as well as A/Emath on the sidelines. Will attend to questions on these subjects, time permitting. Little or no time during the exam period, as I will be focussing on my own students preparation.

Thank you so much for the answer!!! I was stuck on this qn for days XD
Most welcome. Its one of those nasty questions. Whenever you see the need to change A/2 to A or vice versa... its always something to do with the cos2A identity.
