The graph of a function and its antiderivative: a praxeological analysis in the context of Mechanics of Solids for engineering
Résumé
The notion of integral is usually first introduced to engineering students in their calculus courses before later being used in their professional engineering courses. In this paper we analyse the textbooks used as main references in two engineering courses: a calculus course and a mechanics of solids course. Specifically, we compare how each textbook presents the task of sketching the graph of an antiderivative in the context of kinematics. Our results indicate that the mechanics of solids course presents this task by emphasising the notion of area and basic geometric calculations, using different notation and rationale than in the calculus course. We discuss the possible impact of these differences on the training of engineers.
