The course presents the classical tools of infinitesimal and differential calculus, and integral calculus for functions in one and two variables, in addition to geometry and linear algebra, illustrating wherever possible their applications in other disciplines.
The topics will be covered with a view to:
- Acquiring analysis skills: i.e. introducing and becoming accustomed to rigorous discussion and analytical reasoning. - Attaining, through practice, command of an exact and apposite language. - Applying the tools of calculus to prepare for better managing the use of quantitative methods.
Students must be conversant with the following topics:
- Arithmetic and algebra.
- Analytical geometry and trigonometry on a plane.
- Functions: in particular, a knowledge of the definition, graphs and principal properties of the fundamental functions (power, exponential, logarithmic, sine, cosine, tangent). They must also be able to solve algebraic, exponential, logarithmic and trigonometric equations and inequalities.

Examinations
There will be a written exam, held during the sessions scheduled in the academic calendar, and possibly completed with an additional oral exam.
There will also be four intermediate written tests during the course.
Students who earn a grade of eighteen or higher on each of the four intermediate tests can be exempted from sitting the final written exam.
