Just for the sake of a different approach - We can make an observation first. If sin ( α + β) = 1, then cos ( α + β )=0; no matter what values α and β take. Webb29 apr. 2024 · sin ( α − β) = C D = P Q = B Q − B P. In r t Δ A B C, A C = A B cos β and hence A B = 1 cos β, B C = tan β. So in r t Δ A B Q, B Q = A B sin α = sin α cos β. Also in r t Δ B P C, ∠ P B C = α − β and hence B P = B C cos ( α − β) = tan β cos ( α − β). So one has (1) sin ( α − β) = sin α cos β − tan β cos ( α − β). Similarly Webb29 apr. 2024 · My attempt: sin ( α − β) = C D A C = P Q A C = B Q − B P A C = B Q A C − B P A C.
