Web25 Jan 2024 · Trigonometric Functions of Sum and Difference of Two Angles Formulae Derivation Consider the points \ ( {P_1}, {P_2}, {P_3},\) and \ ( {P_4}\) on a unit circle centred at origin such that \ (\angle {P_1}O {P_4} = x,\angle {P_1}O {P_2} = y,\angle {P_4}O {P_3} = – y\) and \ ( {P_4}\) at \ ( (1, 0).\) Web20 Dec 2024 · In trigonometry, defactorisation means converting a product into a sum or difference. The defactorization formulae are: (1) 2 sin A cos B = sin (A + B) + sin (A – B) Proof: As we know that sin (A + B) = sin A cos B + cos A sin B ……………………… (1) sin (A – B) = sin A cos B – cos A sin B ……………………… (2) By adding eq (1) and (2), we get
