The chapters between ( ) are not normally covered by the course and are not part of the examination material.

Exercices

Exercises describe concepts analyzed in the theoretical part. Chapters are : I. Existence and unicity. II. ODE of the first order. III. ODE of higher order with constant coefficients. IV. Autonomous linear systems. V. ODE with non-constant coefficients. VI. Classification of equilibrium.

Assessment method

written exam: 3 hours of exercises taken from those seen during the lectures / TD and are in the syllabus
 
oral examn: presentation on the blackboard of a question of theory in 10-15 minutes, extracted in advance, without notes.
 
The exam score is calculated as follows:
 
- if the student takes both examns and obtains at least 2/20 in each one, then the total mark is given by: (2 x Written mark + 1 x Oral mark)/3
 
- if the student takes both examns and obtains less than 2/20 in at least one or she signs one of the two tests, then the total mark will be 0 (SG)
 
If the total mark is strictly smaller than 10/20, then the student can keep from one exam session to the next (in the same academic year) the written or oral marks if they are higher than 5/20.
