Recently been doing some sums to do with the addition formulae, I can;t seem to get the hang of it. has anyone gor any good guides on how to use it correctly etc
the main part I have trouble is when a question states use the Addition fomulae to prove *equation here* especially the double angle formulae
thanks for the help
