AB - <p style="text-align: justify;">The present work aims to determine the solution of trigonometric functional equation $f$ with involution from group to field by using the properties of involution function, and the solution and Ulam-Hyers stability of the trigonometric
functional equation are also discussed. Furthermore, this method generalizes the
main theorem and gives the supplement in some reference.</p>
