## Learning objectives

Knowledge and understanding.

At the end of the lectures, students should have acquired knowledge and understanding of the numerical field N, Q, Z, R and C, of the numerical sequences and of the differential calculus for functions of one variable.

Applying knowledge and understanding.

By means of the classroom exercises students learn how to apply the theoretical knowledges to solve concrete problems, such as optimization problems.

Making judgements.

Students must be able to evaluate coherence and correctness of results obtained by themselves or by others.

Communication skills.

Students must be able to communicate in a clear and precise way mathematical statements in the field of study, also in a context broader than mere calculus. Through the front lectures and the assistance of the teacher, the students acquire the specific and appropriate scientific vocabulary.

Learning skills.

The student who has attended the course, is able to deepen autonomously his/her knowledge of numerical sequences, differential calculus for functions of one variable, starting from the basic and fundamental knowledges provided by the course. He/She will be also able to consult specialized textbook, even outside the topics illustrated during the lectures. This to facilitate the learning of the other activities of the degree course in Mathematics, which use notions from Mathematical Analysis.

## Prerequisites

They are not required.

## Course unit content

The course aim at providing students with the fundamental notions of the numerical sets and with the fundamental concepts of infinitesimal calculus for functions of one variable and of numerical sequences.

## Teaching methods

The course schedules 5 hours per week of lectures and classroom exercises. During the lectures the fundamental properties of the numerical sets will be illustrated and basic results of calculus for functions of one variable will be analyzed and discussed. Students will be provided also with the basic results on sequences of real numbers. The classroom exercises aim at showing how and where the abstract results can be applied to make the students understand better the relevance of what they are studying.

## Assessment methods and criteria

The exam (Analisi Matematica 1 first part jointly with Analisi Matematica 1 second part) consists of a written part and an oral part in different dates.

Two evaluations in itinere are fixed: if the average of grades of these two test and the evaluation in itinere of the second part of the course Analisi Matematica 1 is not less than 15 points, the student is relieved from the written part of the exam.

The written part (or the evaluations in itinere) is based on some exercises and it is aimed at evaluating the skills of the student in applying the abstract results proposed during the course to some concrete situations.

The oral part is aimed at evaluating 1) the knowledge of the abstract results seen during the course and their proofs 2) the correct use of the mathematical terms, 3) the knowledge of those arguments which have not been included into the written test.
