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 Webb9 mars 2014 · Substituting into our sin(δ + β) equation we get sin(δ + β) = cos(δ)sin(β) + sin(δ)cos(β) . Now we do as we did in our last proof and let β = − ϕ to get sin(δ − ϕ) = cos(δ)sin( − ϕ) + sin(δ)cos( − ϕ) = − cos(δ)sin(ϕ) + sin(δ)cos(ϕ)
