If $ϕ (α, β) = ∣ ∣ ∣ ∣ \begin{matrix} cos α & - sin α & 1 sin α & cos α & 1 cos (α + β) & - sin (α + β) & 1 \end{matrix} ∣ ∣ ∣ ∣,$ then

ϕ (300, 200) = ϕ (400, 200)

∣ ∣ ∣ ∣ \begin{matrix} cos α & - sin α & 1 sin α & cos α & 1 cos (α + β) & - sin (α + β) & 1 \end{matrix} ∣ ∣ ∣ ∣

∣ ∣ ∣ ∣ \begin{matrix} cos α & - sin α & 1 sin α & cos α & 1 cos (α + β) & - sin (α + β) & 1 \end{matrix} ∣ ∣ ∣ ∣

cos (α - β) = sin (α + β)

\frac{1}{1 - sin α} =

\frac{2 sin α}{1 + cos α + sin α} = x

\frac{1 - cos α + sin α}{1 + sin α}

\sin α + \sin β = a and \cos α + \cos β = b

\sin (α + β) = \frac{2 a b}{a^{2} + b^{2}}

\cos (α - β) = \frac{a^{2} + b^{2} - 2}{2}
