20810231 - MATHEMATICAL ANALYSIS I

Allow the acquisition of the deductive logic method and provide the basic mathematical tools of the differential and integral calculus. Each topic will be rigorously introduced and treated, performing, sometimes, full proofs and also making a strong connection with the physical meaning, the geometric interpretation and the numerical application. A proper methodology and a reasonable skill in the use of concepts of the integro-differential calculus and related results will enable the students to possibly face in an easily way the more applied topics that will be developed in the later courses.

Type of delivery of the course

The course plans lectures and exercises. Attendance is not required but strongly suggested.

Type of evaluation

The written exam, aimed to evaluate the student's ability in solving exercises even of theoretical nature, lasts two hours, is composed by a first part with four multiple choice questions and a second part with two open-ended questions. The student might be exempted by the written exam if he passes a written intermediate test on the first part of the course and a final one on the second part of the course, each of two hours, built in a similar way to what described above. In the winter session the student will have the possibility of recovering one of the two intermediate tests.
