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).

Webb23 mars 2024 · Write the following difference of sines expression as a product: sin(4θ) − sin(2θ). Solution We begin by writing the formula for the difference of sines. sinα − sinβ = 2sin(α − β 2)cos(α + β 2) Substitute the values into the formula, and simplify. sin(4θ) − sin(2θ) = 2sin(4θ − 2θ 2)cos(4θ + 2θ 2) = 2sin(2θ 2)cos(6θ 2) = 2sinθcos(3θ) Exercise … Webb29 mars 2024 · Transcript.
