Fundamentals of Mathematical Analysis and Physics.

The student is free to use texts that carry out the topics with at least the same depth as the one dealt with in the lessons. However, it is noted that the lessons have based on the following texts: Massimo Corcione, Note di trasmissione del calore, Editore CISU, ISBN 9788879757515 Parolini G., Del Monaco A., Fontana D., Fondamenti di fisica tecnica (1983) - UTET.

Attendance of the course is not compulsory, but highly recommended.

The written exam can be supported in a written test during the day on which the exam is scheduled. The writing consists of 4 questions each. The total vote is between 0 and 30 with honors. The oral exam, if deemed necessary by the teacher, consists of an interview (after the positive result of the written test) on the day of the written test or in the following days, in case of a large number of enrolled students. The oral is a vote between 0 and 30 with honors. The arithmetic average rounded up between exoneration/written and oral constitutes the final vote of the exam.

Class in presence, or online and hybrid if allowed. Frontal teaching, with explanation on blackboard and powerpoint presentations.
