WebThe correct option is B. sin 2 B. Solving the given function: tan A = 1 2, tan B = 1 3. We know that, cos 2 A = 1-tan 2 A 1 + tan 2 A. Substitute value of tan A. cos 2 A = 1-1 2 2 1 + 1 2 2 = … WebAnswer (1 of 3): If tan (A + B) = √3, cos (A - B) =√3/2 and A > B, then what are the values of A and B? Solution: tan (A + B) = √3, or A + B = arc tan √3 = 60º. cos (A - B) =√3/2 or A - B = arc cos √3/2 = 30º. 2A = 90º or A = 45º and B = 15º. Answer.
