Superstability of Some Pexider-Type Functional Equation
Journal of Inequalities and Applications volume 2010, Article number: 985348 (2010)
We will investigate the superstability of the sine functional equation from the following Pexider-type functional equation (), which can be considered the mixed functional equation of the sine and cosine functions, the mixed functional equation of the hyperbolic sine and hyperbolic cosine functions, and the exponential-type functional equations.
