A Euler¡¯s formula for hyperbolic functions is considered a consequence of a unifying point of view. Then, the unification of Jordan, Lie, and associative algebras is revisited. We also explain that derivations and co-derivations can be unified. Finally, we consider a ¡°modified¡± Yang¨CBaxter type equation, which unifies several problems in mathematics.
