Sin(a - b) is the trigonometry identity for the compound angle that is given in the form of the difference of two angles. Sin A. Sin B = [Cos (A – B) – Cos (A + B)]/2; Sin A. Cos B = [Sin ( ... Feb 18, 2025 ... If A=60 and B=30 verify at sin(A+B)=sinAcosB+cosAsinB | #pyq2024 #smartedutech #trignometry. https://www.youtube.com/. Like Comment. Share. Copy The “big three” trigonometric identities are sin2 t + cos2 t = 1. (1) sin(A + B) = sinAcosB + cosAsinB. (2) cos(A + B) = cosAcosB − sinAsinB. The correct answer is “Option C”. Note: In solution part we cut off tan B from cot B because they both are inverse of each other. ... sinb)(cosacosb+sinasinb)=cos2acos2b+cosacosbsinasinb−cosacosbsinasinb− ...
