Because of its many uses, the constrained optimization problem is presented in most calculus courses for mathematicians but also for economists. Looking at Lagrange's Theorem we are interested in studying the teaching of this theorem in both branches of study, mathematics and economics. This paper faces a twofold objective: first, we show the methodology of our research project concerning the didactic transposition of Lagrange's Theorem in university mathematics courses. Secondly, we would like to compare two mathematics courses given at the universities of Namur and Louvain by means of the "Anthropological Theory of Didactics" of Yves Chevallard. [less ▲]
