The 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). Therefore, 0 = B2 − 1 0 = (B + 1)(B −1)
Trignometrical Formulae sin(A+B) = sinA cosB +cosA sinB sin(A−B) = sinA cosB −cosA sinB cos(A+B) = cosA cosB −sinA sinB cos(A−B) = cosA cosB +sinA sinB
