The objective of this research is to contribute with the study of sine function by situations that involve the use of computer in a connection between Mathematics and Physics. This dissertation directs to investigate how a pedagogical strategy presented by a sequences of activities using the software Winplot, may promote the learning of sine function for the students in high school (second year in Brazil). Furthermore, it is a way to verify if there is a possibility to contribute in the comprehension of a physical-mathematical context. The Theory of the Didactical Situations developed by Guy Brousseau (1986) as well as the Theory of Semiotic Registries developed by Raymond Duval (2003) supported this research. The Didactical Engineering by Michèlle Artigue (1988) was the methodology research used. The students were proposed five sequences of activities. The one called Part I investigates the previous knowledge the students had in relation to the polynomial functions among them the ones with degrees one and two, constant and sine. In the activity called Part II, students used the software Winplot to build the graphs and analyze the changings promoted by the coefficients and the independent term for the function of degree two. In the activities called Part III and Part IV, the students analyzed the characteristics of sine function like amplitude, domain, range and period. For doing that, they built the graphs using the software Winplot. In the last activity called Part V, the students we supposed to observe the connection between Physics and Mathematics. This connection have been showed by a sequence of activities taken down from a material called Student Notebooks of Physics that brings the study of sound waves being associated with the sine function. Some difficulties of the students in the conversion from the algebraic register to the natural language register and vice versa even as the conversion from the graph register to the algebraic register and vice versa were observed. As a result, it was possible to notice that the proposed sequence of activities with the use of software Winplot can contribute to the comprehension of the students if the subject has a connection with another one. In the case of this sequence, this connection happens between wave sounds (Physics) and sine function (Mathematics)
