Abstract
We propose the use of two point Pade approximants to find expressions valid uniformly in coupling constant for theories with both weak and strong coupling expansions. In particular, one can use these approximants in models with a strong/weak duality, when the symmetries do not determine exact expressions for some quantity.

11 pages, 5 figures; fixed references, typos and corrected the sloppy version of the convergence theorem we quoted with up to date references on Pade convergence
