Summary We consider Lagrange interpolation involving trigonometric polynomials of degree ≦N in one space direction, and piecewise polynomials over a finite element decomposition of mesh size ≦h in the other space directions. We provide error estimates in non-isotropic Sobolev norms, depending additively on the parametersh andN. An application to the convergence analysis of an elliptic problem, with some numerical results, is given.
