WebbThe trigonometric identity sinA + sinB is used to represent the sum of sine of angles A and B, sin A + sin B in the product form using the compound angles (A + B) and (A - B). It says sin A + sin B = 2 sin [ (A + B)/2] cWe will study the sin A + sin B formula in detail in the following sections. Sin A + Sin B Sum to Product Formula Webb3 sep. 2024 · sin (A – B) = 1/2 Since A, B are acute angles, Therefore A – B should also be acute angle The acute angle for which the value of sin is 1/2 = 30°. Therefore, sin (A – B) = sin 30° = 1/2 A – B = 30° ⇢ (i) The acute angle for which the value of cos is 1/2 = 60°, therefore, cos (A + B) = cos 60° = 1/2 A + B = 60° ⇢ (ii) Adding equations (i) & (ii),
