The problem considered is as follows: given C⊂RnC\subset \R^n and F:C→RnF:C\rightarrow \R^n differentiable, find f:C→Rf:C\rightarrow \R differentiable such that ∥∇f(x)∥−1∇f(x)=∥F(x)∥−1F(x)\norm \nabla f(x)\norm^{-1} \nabla f(x) = \norm F(x) \norm^{-1}F(x) for all x∈Cx\in C. Conditions for ff to be pseudoconvex or convex are given. The results are applied to the differentiable case of the revealed preference problem.
