We show that this Hida-Malliavin derivative defined on $L^2(\\mathcal{F}_T,P)$ is a natural extension of the classical Malliavin derivative defined on the subspace $\\mathbb{D}_{1,2}$ of $L^2(P)$. The Hida-Malliavin calculus allows us to prove new results under weaker assumptions than could be obtained by the classical theory.
