The stability of the functional equation F (x + y) -G(xy) = 2H (x)K(y) over the domain of an abelian group G and the range of the complex field is investigated. Several related results extending a number of previously known ones, such as the ones dealing with the sine functional equation, the d'Alem
In this paper, we will introduce a new multiplicative functional Eq. 1 and prove ลฝ . that the given equation is equivalent to the well known ''original'' one, f xy s ลฝ . ลฝ . ลฝ . f x f y . Moreover, we will investigate the stability problem of Eq. 1 in the sense of R. Ger.
