This mathematics course is dedicated to learning and mastering Analysis 1 and Analysis 2. It is aimed at students wishing to strengthen their foundations or deepen their knowledge of differential and integral calculus. Having myself taken these courses at EPFL (École Polytechnique Fédérale de Lausanne) with very good results, I understand the academic expectations as well as the common difficulties encountered by students. We will cover fundamental concepts such as limits, continuity, derivatives, integrals, as well as sequences and series. Particular attention will be paid to understanding the concepts and solving typical exercises. The course is tailored to each student's level, with clear explanations, concrete examples and personalized support to progress effectively, especially in preparation for exams.
