Multiple-angle formulas of generalized trigonometric functions with two parameters

Abstract Generalized trigonometric functions with two parameters were introduced by Drabek and Manasevich to study an inhomogeneous eigenvalue problem of the p -Laplacian. Concerning these functions, no multiple-angle formula has been known except for the classical cases and a special case discovered by Edmunds, Gurka and Lang, not to mention addition theorems. In this paper, we will present new multiple-angle formulas which are established between two kinds of the generalized trigonometric functions, and apply the formulas to generalize classical topics related to the trigonometric functions and the lemniscate function.
