Objectives

1. Knowledge and understanding. The student will acquire theoretical and practical knowledge of the topology of the Euclidean spaces, the theory of functions of several real variables, optimization, integral calculus in several variables, the theory of curves and surfaces, and vector fields. 2. Applying knowledge and understanding. The student will be introduced to the main applications of analytical methods to geometric and physical problems. 3. Making judgements. The student will learn how to classify single problems of optimization, calculus of volumes and areas, vector fields in the right class and which method to apply. 4. Communications skills. The course deals, in a somewhat simplified way, with subjects of higher mathematics and aims at providing the student with a rigorous scientific language. 5. Learning skills. Thanks to the notions acquired in this course, the student will be able to address most problems arising in applied science and engineering.

Objectives

1. Knowledge and understanding. At the end of the course the student will have knowledge of topics concerning real sequences, the infinitesimal calculus of real functions of a real variable.
2. Applying knowledge and understanding. The student will be introduced to the main applications of the theoretical notions of the course, concerning both the solution of mathematical problems and the study of physical problems.
3. Autonomy of judgment. The student will learn how to classify single problems of differential and integral calculus.
4. Communicative Skills. Students will acquire the ability to communicate what they learn and elaborate and also to express and argue the choice of methodology with respect to another to solve a mathematical problem.
5. Learning skills. Thanks to the notions acquired in this course, the student will be able to perfect his knowledge of higher mathematics and its applications to engineering.

Teaching Methods

Lectures: 50 hours. Exercises: 30 hours. Theory and exercises will be dealt with together, in order to emphasize the close connection between various aspects of the subject. The course will be enriched by tutoring, simulated exams, and a constant support to students. Blackboard, slides, and occasionally calculus software will be employed. The course notes, aimed at complementing the suggested texts, will be made available in due time.

Teaching Methods

Frontal lectures (theory): 50 hours
Frontal lectures (exercises): 30 hours

Verification of learning

The verification test consists of two parts: a written test and an oral test. The written test consists of 4 exercises related to optimization, integration, differentiation, series. In order to access the oral exam a vote is required. not less than 18/30. To the oral is required the knowledge of the theory related to the exercises carried out in the written test. Priority will be assessed: knowledge of contents, autonomous processing capacity, exposure capacity.
