Students sitting AS or A Level Further Mathematics papers may be required to use the formulae that were introduced in AS or A Level Mathematics papers. A modification of the compound angle formula allows you to simplify expressions such as 4 \sin \theta+3 \cos \theta and to solve equations. In order to find a single expression for 4 \sin \theta+3 \cos \theta his is matched to the compound angle formula r \sin (\theta+\alpha) because this has sinθ in the first term and cosθ in the second term as well as a plus sign.

\begin {gathered} 4 \sin. Last week, I taught my class on the topic of R-formula in A-Maths Trigonometry. I highlighted that schools taught the usage of the two formulas as shown: In my years of teaching, I have also come across schools which have insisted students to understand and use the full derivation of R.
