We analyze 504 curricula of engineering degrees in Argentina and 125 syllabuses of the courses of Linear Algebra (LA) and Analytic Geometry (AG) in the period 1810-2021. We aim to investigate the transformations of such knowledge to be taught from four stages defined in the research. Yves Chevallard's Anthropological Theory of Didactics is adopted as a theoretical reference. The results show the changes in the LA and AG knowledge necessary for the formation of engineers in each stage and the reasons for these transformations are analyzed.
