The aim of the course is to provide the student with the general bases of differential calculus for the study of real functions of a real variable and basic concepts of analytic geometry, trigonometry and linear algebra (vectors and matrices). Expected skills: knowing how to interpret the graph of a function, knowing how to determine the probable graph of a function, knowing how to solve a triangle using the theorems of trigonometry, knowing how to apply the knowledge of analytical geometry and goniometry to real contexts.
