However the on-line material found in virtuale should be enough for the theorical part but probably not for the exercisesTeaching methods
The course consists of lessons describing the fundamental concepts of real and vector functions of several real variables, vector fields in R^n and of linear differential equations and some hints to nonlinear ones. Lessons are completed with examples and counterexamples illuminating the theoretical content. Futhermore a lot of exercises are solved in the classroom.
Assessment methods
The assessment is divided in 2 tests and the student needs to pass the first test to be admitted to the second.
The first test will be a written exam where the student will solve some exercises, and he will be admitted to the second test if he recieves a mark greater or equal to 15/30.
The second test will be a theorical one, meant to verify the comprehension of the definitions, the theorems and their proofs.
Through this theorical exam he may gain up to 6 points but the grade may also decrease and the student may also fail it.
