Given a semigroup equipped with an involutive automorphism , we determine the complex-valued solutions of the functional equation \begin{equation*}f(xσ(y))=f(x)g(y)+g(x)f(y)+h(x)h(y),,,x,y\in S,\end{equation*} in terms of multiplicative functions and solutions of the special cases of sine and cosine-sine functional equations.
