Subject fundamentals
The course Geometry has two principal aims. The first one is teaching students how to analyse a problem and solve it through a deductive path using a mathematical language. The second aim is to present an array of topics spread over Linear Algebra, Elementary, Differential Geometry and the Theory of Multivariable Functions, which thus build a bridge to the Analysis I and II courses. Part of the subject matter is in fact dedicated to extending differential calculus from one to several variables, and touches upon the basic applications. Moreover, the Geometry of Euclidean spaces is a necessary tool or integral calculus, as treated in Mathematical Analysis II.
Expected learning outcomes
Ability to follow proofs; understanding of the essential properties of elementary geometry of space, the basics of vector spaces plus continuity and differentiability of multivariable functions.
Prerequisites / Assumed knowledge
Real and complex numbers, trigonometry, equations and inequalities of degree one and two, differential calculus in one variable.

Assessment and grading criteria
The final evaluation will be made with a written examination (10 multiple choices questions and 2 exercises). However, an oral colloquium can be request by the teacher.
