Student in L3 fundamental mathematics and former student of prep and school of engineering offers courses in mathematics and physics for all levels. I want to advance the student based on the following points that I think are essential for a good knowledge: -Verification of knowledge -Explain the essence of the course and highlight existing links between the various chapters of the program. -Presentation of the other notions of the course in the form of corrected exercises. -Exerices ranging from the direct application of the course to the most original and constructive by trying to present in a synthetic way and compliant some pretty accessible theories. -Recapitulation of the course and summary of the essential knowledge of each chapter.
