The main objective of the present work is to analyze the coordination of the Representations in the Registries of Semiotic Representation (graphic-algebraic-natural language), that students of Economics, of a public university in Lima, perform when they develop a problem issue related to the Lagrange Multiplier (LM) to carry out this thesis, we have reviewed research backgrounds that has have as a mathematical object of study the LM, whether it is with the use of technology or without it. Also, we have reviewed and analysed the applications that are presented in the experiments carried out in those investigations, as well as the use of the instruments used for data collection, which serves as a guide for the design of the activities present in the problem situation . On the other hand, we have justified the realization of our research taking into account the academic, curricular, personal and professional aspects in order to show the relevance of the execution of our work. The theoretical framework use is that of the Theory of Registries of Semiotic Representation (TRRS) of Duval (1995), provides us with valuable and necessary tools to understand and interpret the transformations made by the subjects of research when a problem situation occurs. Likewise, we have chosen as a methodological reference aspect of the Didactic Engineering (ID) of Artigue (1995) whose structure will guide our tesis. To carry out the experimental stage, we have chosen two couples who will participate in a problematic situation, composed of two activities, in wich they used the Geogebra software for its realization. Finally, an analusis was made of the results obtained from the problematic situation, in wich we compared the a priori analysis and the a posteriori analysis, the characteristic of the ID, to observe whether the results were or were not predicted by the researcher. Thus, it is conclude that the use of the GeoGebra software favours the conversion of representations in the algebraic register for representations in the graphic register. On the other hand, the TRRS allows us to explain how conversions and treatments are developed, also to identify the difficulties for which students do not manage to coordinate.
