The programs in force for several years invite Mathematics teachers to insist more on the notion of skills to be acquired by their students rather than on the subject matter strictly speaking. This implies that the student will have a different attitude towards his courses in the sense that he will be asked to provide a greater personal effort. He becomes responsible for his training, he will have to be the real one actor. However, I will be available to anyone interested in helping them to properly assimilate mathematical approaches and to model things in order to fully understand mathematical concepts, whatever their objectives (revision for exams, personal interest, etc.). The main objectives of this course are as follows: -acquire certain mathematical reflexes and automatisms, particularly in calculations algebraic, directly recognize a particular situation where such formula or theorem. -establish clear links between theory, direct application exercises and exercises overview. -develop certain forms of creativity and imagination within the rigid context of a well-established theory defined.
