The course aims to provide the student with fundamental methods and techniques of Mathematics, with particular reference to the foundations of linear algebra, to differential and integral calculus for the functions of a real variable, to the study of sequences and numerical series. The course provides knowledge of the main notions of mathematical analysis and mastery in the management of calculus. The student will be able to formulate a basic logical and deductive reasoning, with particular reference to mathematics in general. A further objective is the preparation of the student for the application of analytical techniques to other scientific disciplines. The acquired notions will allow the student to understand which mathematical models and techniques are most appropriate for the description of engineering systems. The student will acquire the ability to communicate what has been learned and processed and also express and argue the choice of one methodology over another for solving a mathematical problem.
