### Learning Objectives

The course is aimed at the acquisition of the theoretical and applicative principles of basic mathematics. The aim of the course is to present the main notions of elementary algebra and mathematical analysis. In particular, the tools necessary for the qualitative study of the real functions of a real variable will be introduced. For this purpose, the fundamental notions of differential and integral calculus for real functions of one real variable will be presented.

### Learning Achievements (Dublin Descriptors)

Knowledge and understanding. At the end of the course the student must have acquired a good knowledge of the mathematical topics covered in the course. He must be able to argue correctly and with language properties on the topics covered in the program. Examples and working methods are shown in the classroom during the lessons and proposed in the exercises.

Applied knowledge and understanding. At the end of the course the student must have acquired a good ability to use the main tools of basic mathematics. He must be able to correctly apply the formulation studied and must be able to solve general mathematical problems similar to those studied. In particular, he must be able to apply the acquired knowledge even in contexts slightly different from those studied, and have the ability to use the acquired knowledge to independently solve problems that may appear new. Examples of such applications are shown in the classroom during the lessons and proposed in the exercises.

Autonomy of judgment. At the end of the course the student must have acquired a good ability to analyze topics and problems in general mathematics, the ability to critically evaluate any proposed solutions, and a correct interpretation of similar topics.

Communication skills. At the end of the course the student must have acquired a good ability to clearly communicate his / her statements and considerations concerning general mathematics problems. The working method is shown in the classroom during the lessons and proposed in the exercises.

Ability to learn. At the end of the course the student must have acquired a good capacity for autonomy in the study of the discipline, in the reading and interpretation of a qualitative phenomenon, in the search for useful information to deepen the knowledge of the topics covered.

Assessment

The expected objectives are verified through the following two tests, both mandatory:

1. A formative assessment test: consisting of a written paper - lasting 2 hours - divided into five exercises on the following topics:

Set theory: relations; functions between sets; combinatorics;
Real numerical sequences;
Complete study of a real function of one real variable;
On the properties of continuity and differentiability of real functions of one real variable;
Integrals of a real function of one real variable; calculation of areas of flat domains.

2. An oral interview: consisting of the discussion of the written paper and three open questions on the theoretical topics covered in the course.

For both tests, the evaluation criteria are as follows:
- relevance and effectiveness of the responses in relation to the contents of the program;
- the level of articulation of the response;
- adequacy of the disciplinary language used.

The overall evaluation is expressed with a mark out of thirty taking into account both tests.

Disabilità e DSA

Le studentesse e gli studenti che hanno registrato la certificazione di disabilità o la certificazione di DSA presso l'Ufficio Inclusione e diritto allo studio, possono chiedere di utilizzare le mappe concettuali (per parole chiave) durante la prova di esame.

A tal fine, è necessario inviare le mappe, due settimane prima dell’appello di esame, alla o al docente del corso, che ne verificherà la coerenza con le indicazioni delle linee guida di ateneo e potrà chiederne la modifica.

### Notes

During the course, several exercises will be proposed to be carried out on the theoretical topics covered in class.

These exercises will be functional to the overcoming of the expected written paper.

Students are strongly advised to do them.

It is advisable to consult the following text which aims to show mathematics and the associated calculation tools how they could be used to consult and clarify a large number of biological phenomena:

Bodine Erin N. Suzanne Lenhart Gross Louis J. Caristi G. (cur.) Mozzanica M. (cur.) Tommei G. (cur.), Mathematics for the life sciences, UTET University, 2017.

Some simple models taken from the quoted text will be proposed as an exercise during the course.

We also suggest the following text which contains over 500 exercises carried out useful for understanding the main theoretical topics covered during the course:
