MATHEMATICAL ANALYSIS I J - Pr

The aim of the course of Analisi Matematica I is to give the basic skills real and complex numbers, differential and integral calculus for real functions of one real variable.

In particular, the learning objectives of the course, according to the Dublin descriptors, are:

• Knowledge and understanding: The student will learn some basic concepts of Mathematical Analysis and will develop both computing ability and the capacity of manipulating some common mathematical structures, as complex numbers, limits, derivatives and integrals for real functions of one real variable, numerical series.
• Applying knowledge and understanding:The student will be able to apply the acquired knowledge in the basic processes of mathematical modeling of classical problems arising from Engineering.
• Makin​g judgements: The student will be stimulated to autonomously deepen his/her knowledge and to carry out exercises on the topics covered by the course. Constructive discussion between students and constant discussion with the teacher will be strongly recommended so that the student will be able to critically monitor his/her own learning process.
• Communication skills: The frequency of the lessons and the reading of the recommended books will help the student to be familiar with the rigor of the mathematical language. Through constant interaction with the teacher, the student will learn to communicate the acquired knowledge with rigor and clarity, both in oral and written form. At the end of the course the student will have learned that mathematical language is useful for communicating clearly in the scientific field. Learning skills: The student will be guided in the process of perfecting his/her study method. In particular, through suitable guided exercises, he/she will be able to independently tackle new topics, recognizing the necessary prerequisites to understand them.

The course is divided into two parts. The first partdeals with the construction and the properties of the field of real numbers, complex numbers, basic topology notions, sequences and functions, differential calculus and its applications. The second part deals with series and integrals. The lessons are complemented by exercises related to the topic of the course and both the lessons and the exercises will be carried out in frontal mode and/or online, according to rules determined by the department. Should teaching be carried out in mixed mode or remotely, it may be necessary to introduce changes with respect to previous statements, in line with the program planned and outlined in the Syllabus.
