There are six so called addition formulae often needed in the solution of trigonometric problems In this unit we start with one and derive a second from that Then we take another one as Summary Continuing with trig identities this page looks at the sum and difference formulas namely sin A B cos A B and tan A B Remember one and all the rest flow from it There s also a beautiful way to
Trig Addition Formulas The trig addition formulas can be useful to simplify a complicated expression or perhaps find an exact value when you only have a small table of trig values For The derivation of the trigonometric addition formulas using the definition of the dot product The definition of the dot product was used in Section 1 7 to provide a straightforward
