to aqa I sent an email
ie please use the formula Area=1/2ab sin C to mean you can label the triangle in the same way as for the cosine rule a^2 =b^2 +c^2 -2bc con A.
I’m sorry I don’t have your name but to respond to your query we have a common formula sheet at the moment between all of the exam boards which we won’t be changing until after 2016.
From 2017 there will be no formula sheet given to students as the new Reformed GCSE in Maths requires most of the current formulae to be learned.
Best wishes,
Shaun Procter-Green (Qualifications Manager)
