Please make formulae consistent on gcse/igcse maths exam paper

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.

A lot of people are confused because they do real;ise they have to relabel the triangle.

I just sent this email to aqa.
