Abstract

The aim of this paper is to study the superstability for the mixed trigonometric functional equation:                                                            and the stability of the Pexider type functional equation:                          where  G is any group, not necessarily abelian  f , g and  h are unknown complex valued functions and σ is an involution of G.   As a consequence we prove that if f satisfies the inequality   for all x , y ∈ G then  f is bounded.
