In electronics, we often get expressions involving the sum of sine and cosine terms. Jan 4, 2016 ... Trigonometric and Geometric Conversions, Sin(A + B), Sin(A - B), Sin(AB) Sin(A + B) is not equal to sin A + sin B, sin(А - B) = ?, Sin( cos(A + B) = cosAcosB - sinAsinB cos(A - B) = cosAcosB + sinAsinB sin(A + B) = sinAcosB + cosAsinB sin(A - B) = sinAcosB - cosAsinB. ** See other side for ... sin b sin a = (ba) cos c⇒ |sin b − sin a| |ba||cos c|. - al cos cl. But |cos c≤ 1 and so sinb - sin a| ≤ |b − a| and, combined with the previous ... The “big three” trigonometric identities are sin2 t + cos2 t = 1. (1) sin(A + B) = sinAcosB + cosAsinB.
