Posing X = x+y and Y = x−y, the determinant becomes: Δ = ∣∣∣∣∣∣∣ cos(X) sin(Y) sin(X +Y) sin(X) cos(Y) 0 −cos(X) sin(Y) sin(X −Y) ∣∣∣∣∣∣∣ ... From the comment by GWu: Your general solution involves e^ {ix} and xe^ {ix}. So if you want the particular solution with \sin x and \cos x (which are disguised forms of e^ {ix} and e^ {-ix} ...
sin(θ + 2πn) = sin(θ); cos(θ + 2πn) = cos(θ); and For example a trig function at 90° (π/2) will be mathematically the same as at 450° (5π/2), as 5π/2 = π/2 + 2π.
